(Kiev) VIAU; none TITLEt Optimal detectionl/@of signals by a spatially distributed reception syst SOURCE: AN SSSR. Izvestiya. Tekhnicheskaya kibernetika, no. 3, 1966, 126-134 TOPIC TAGS: signal detection, antenna array, random noise, radio reception ABSTRACT, An approach, based on the general theory of detection, to the problem of the synthesis of equipment for the space-time detection of signals is presented. A solution is found for the problem of synthesizing an optimum distributed (diversity) signal detection system, designed to operate against the background of a random inter- ference field. The general correlations obtained in the paper may be used when analyzing the quality of detection of signals of finite length by two-point receiving equipment with an infinite time base. Using this type of detection system and a four-dimensional space-cime continuum (the direct product of infinite three-dimension- al space and an infin-.te tima interval), the authors show that the method of space- time signal selection makes possible a substantial improvement in the quality of signal detection. This finding is in agreement vith previously published results (V. D. Volkovich, Yu. 1. Samoylenko. Sb. "Slozhnyye sistemy upravleniya", "Naukova Card 1/2 L 0626FJ-67 AP60 Dumka", ser.

An integral equation of the received signal (with a limite& dispersion of noise field intensity) is set up and transformed into a first-kind Fredholm-type equation having a Caueby kernel. By construct;ng a sequence of linear.@ functionals with a contiTmou weight function, it is proven that the distributed reception system-ensures an almost regular channel of communication. The near_ regularity characteristic is inherent to a wide alass of distributed.channels with additive noise which can bedescribed by an operator with a nondegenerate kernel.

For that purpdse it is necessary to unsolder both metal sidepleces from the ceramic body,, remove all content from the tube and clean it thoroughly. Then the sidepieces should be remotmted on the body with one end of the winding wire fastened to one of them. After winding the required number of turns the other end:6f the wire should be affixed-to the second sidepiece. The coil is then glued to the ceramic body.@ Inductance adjustment of the coil is achieved by unwind- ing the superfluous turns. AVAILABLE: Library of Congress Card 1/1 SMIOYLIKOV, K.

A group at the works proposed the automation of the wet- grinding department (Figure 1). Here, the crushed bauxite has up to 5% lime added, the mixture being discharged from the bunker by a plate feeder and conveyed to the ball mill to wh-ich return solution and fresh alkali are added. The pulp goes to a classifier, where return solut-ion is added, and then to a hydrocyclone. The pulp from the hydro- cyclone goes via mixer tanks to the leaching sector. The objects of the automation work were to concentrate control of the main equipment at the central control point and to make the operation of the main units automatic under conditions set centrally by the controller. The following operations have been automated. The addition of return Cardl/3 solution by local float-and-valve devices (Figure 2) and SOV/136-58-6-4/21 Integrated Automation of a Bauxite Wet Grinding Department also the distribution of the solution between mills and classifiers and solution feed i@rom the collector tank to the distributing device (Figuye 3).

After describing the automation of the above operations, the.authors outline the instrumentation and the system of interlinking and overall process control in the wet-grinding department. An alarm system indicates the failure of a unit. The switching on and off of the bauxite-bunker vibrators is to be automatic.

The article deals with the theory of an LC--type divider and that of a zombined divider. The diagram of a simple LC divider is shown in Figure 1; , 11-bis consists of a resonant circuit and a feed-back circuit and compr1ses a source of the synchronising.voltage. The amplitude and phase of 'he system are governed by the foJilowing simplified equations: 2 Joa UM (9) d Cardl/4 Frequency Divider with a Direct Lock-in d 'C_ U M 100 SOV/109-4-1-7/30 (10) whare 1@- WO t In these equations Je and J.0 are defined by Eqs (3) in which � a denotes the amplitude of the aLode-pu.Ise current; Q denotes the quality factor of the resonant circuit, while Nt is defined'by Eq (6) in whi!@h w H is the nominal frequen--y of the system; w H is n times smaller than the frequency of the external electro- mot've force. The steady-state amplitude U .L. mo and the stea1y-state phase w CT are defined by Eqs (12) and (13)- These equatioas can be used to analyse the LC divider shown in Figure "-/:. In this, the righthand-side tube converts a sinussidal voltage into re-,tangular phase-inverted pulses whi-@h are fed to the grid of the lefthand-side tube. The Card2/4 externa .-, synch--on-ising signal is in the form of a train of SOV/109-4-1-7/30 Frequency Divider with a Direct Lack-In re-tang-alar pulses; this is also fed to the grid of the ieithand--3-ide tube. Consequently, the tube is conducting when bcth the voltages at the grid are equal to zero and it is closed when one of the voltages is negative. The envelge of the anode current pulses can be expressed by Eq (it"), where i. is expressed by Eq (18), where Ri is the internal resistance of the lefthand-side tube. The parameters JCa and J. 0 ian, therefore, be written in the form of Eqs (19) and (20). The steady-state amplitule U . and steady-state phase shift (pCT can be w-ritten as Bqs (28) and (29). The synchronisation bandwidt-h of the divider is defined by Eq (31) in which in J %akr_ g van bv Eq (27). The following notation is is the length of the synchronising auap-ted n Eq (27) It 0 pul3a expressed as a fractio-n of the oscillation period, T_ is the iength of the pulse produeed by the righthand- Oide t'_-@t5 (expressed as a fraction of the oscillation Card3/4 pe:_!,icd) anti T01-T ;s def-Lned by Eq (25). When the internal Frequency Dividex with a Direct Losk.---'-n SOV/109-4-1-7/30 resistance cf the tube is infinite, the amplitude and the phase are expressed by Eqs (33) and (34), respectively. If -14-he synrhronising pulses are in the form of a sinusoidal signal, the parameters J0m and J.0 are expressed by Eqs (:8) and (39), respectively; in this case, it is found that 'rhe eyne.'IlirorrLisation bandwidth is about W6 lower than in the presence of rectangular synchronising pulses. Large ,%7r,cb-'ronising bandwidths can be obtained if a combined -'4.1.vider conzisting of a relaxation oscillator and an LC is used. B-Lock s--hematic of such a divider is shown in Figure 12, and its wavefcrms are sketched in F-4g,-'-e 1'7. The above analytical investigation was 7:roz,rcborated by the experimental data obtained by the authors from a a-imber of special measurements. There are 14 figures and 5 Soviet references.

TITLE: Analysis of the error of phase-shift frequency meters PERIODICAL: Izvestiya vysshikh uchebnykh zavedeniy, Radiotekhnika, 1961, Vol.4, No.1, PP. 55-63 TEXT: The phase-shift frequency meter is based on the use of a four-pole with linear phase characteristic in the operating range of frequencies, and the measurement of the phase-shift of the unknown signal after passage through the four-pole. The authors' previous work (Ref.l: A.I. Danilenko, Radiotekhnikag 1957, Vol.12, No.5, 67, Ref.2: A.I. Danilenko, A. Avdeyenko. Radio, 1958, No.12, 28) indicates that the method is simple and precise. There are three basic sources of error: instability of the four-pole frequency-phase characteristic; instability of the group delay of the four-pole; phase meter error. Departure from nonlinearity of the four-pole characteristics is neglected in this analysis since it can be taken into account in the initial calibration. Assuming independence of the three sources of error they can be added in quadrature. A qualitative idea of the error behaviour is Card IA 24225 Analysis of the error of phase-shift... S/142/61/004/001/004/008 Ei4o/E163 given in Fig.2, where 6. is the error in the frequency-phase characteristic, 6,@ is.the group delay error, 6 T is the phise meter error, and .6ntA is the resultant. As the frequency increases the errors 6, and 6 decrease asymptotically to zero. The error 6T decreases as the-Trequency approaches the frequency of zero phase shift in the four-pole. Furthermore, the rate of approach to zero of 6 (P increases with increase of T, simplifying the requirements on the phase meter.

A general Integral expression is found, into which parameters of specific four-poles can be substituted. Examples are given for phase meters using single-tuned and double- tuned resonant filters as the phase-Sihift network. There are 3 figures and 5 Soviet references.

The essence of the method was reported in earlier articles by this author (Radiotekhnika, 1959, 4, no. 1, 43, and 1958, 1, no. 3, 362). The case of an oscillatory circuit with a nonlinear @,pac.tance is dealt with.

Mosk. energ. in-ta, vYP- 55, 1965, 145-152 TOPIC TAGS: frequency division, frequency divider A5 ABSTRACT: The problem of frequency division by 2 by means of a nonlinear capacitance is considered. Excitation conditions and resonance curves with and without an inertial nonlinear negative resistance are determined from differential equations and a phase portrait. WIth ratios 3, 4 and higher, the reciprocal nonlinear capaci- tance is approximated by a trinomi.al. The second and third harmonies of current are taken into account. The cases with and without periodic solutions and their stability are considered. A study of the phase-plane topology shows that, with a certain amplitude of the external force., a stable singular point exists and, therefore, the division is possible. However, initial conditi6ns are necessary which would keep the operation near the singular point. Thus,.with a sufficient amplitude of synchronizing curiefit'And with'a sufficient capacitance nonlinearity, a hard excitation results; the system should be somehow excited in order to perform Cnrcl 1/2 UDC2 621.396.622 L 33395-66 ACC NR:AR6012310 division. On an oscillation collapse, the division is not restored by itself. Stable division can be obtained by connecting an inertial negative resistance (tunnel diode, dynatron oscillator, etc.) to the circuit. In this case, the division band is widened. The nature of oscillation limiting plays an important part in the above phenomena. Experimental studies with a dynatron.osciUator corroborated some theoretical claims, specificaIlys the presence of hysteresis in the system. With the negative resistance'# the division by 3, 4,-and 5 was observed. Without the negative resistance, only division by 2 was observed. With certain external-current amplitudes, the division by 3 persisted also without the nega@ive resistance, but did not reestablish itself on oscillation collapm Eleven figureV* Bibliography of I title.
