These are given more explicitly by (3) and (4) in terms of the basic probabilities of the appearance r~f the signals. The signals themselves and the noise backgrvv-nd ara defined in (5), (6) and (7) in terms of random quantities, the distributions themselves are defined in (8) and (9). Using these definitions the Ltiequali-cies (1) and (2) can be expanded into (10) and (11)~ In amplitude telegraphy two cases are distinguished, in each case the signal has a Rayleigh distribution and the phase is equiprobable. In the first case the mean square deviations of the Card 1/3 signal components are equal and the probabil-ity of sov/io6-59-3-3/12 The Potential Noise Stability of Sig-,&Is In AM-plitude and T-c-Channel- Frequency-Telegraphy with Fading incorrect reception is given by (31). In the second case the mean square dev!at!;7,ns are -anequal and the corresponding probability is gi--,ren by (46). Comparison of these last two equations shows that the *robatility of inc.:;rrect reception incr,~asas with tha_ asynunetry in between the deviations. With -r-*o-c~hannel frequency telegraphy four signals in all must be considered whose overall probability is given by the system of Bayes equations in (47). The separete contributions are defined in (48) to (51)~ Tb-~ :onditions fcr c_~rrect reception in terms of the rand),m comp,)nent amplitudes aregiven by (57). The probatllity of erroneous reception of a signal in the telegraph channel is given by (60) and making the approximations which are found here, the resulting expression (61) ia seen to differ from that previously quoted by the author for a simple frequency Card 2/3 channel by only 200%, hence it is concluded that present sov/io6-59-3-3/12 The Potential ?- ise Stability of Signals in Amplitude and Two-Channel- Frequency-Telea-gphy with Fading methods of reception are not far from ideal.

From th~ formul4e which are derived it is clear that the probability of -tneorrect--reception depends on the stored amplitu,~e of the total OFal in the preceding interval; this is' termed U. It is a random jalue correlated with the amplitude in the yet preceding intervalp e~c-; it obeys the Rayleigh law. The prc-ba- bility is determined of prkor in receiving the signal A(t) in JoA f, signal A(t) was also transmitted in (i-1) and the amplitudes A El;,L I nals in all preceding intervais Nassume all possible values; the .' 9- t-,*:'* error probability is r I + -2 2a2 a. + al p2 P(B instead of AA),~, r ( 2r, 11. - - n ,)+ a# (I - R9 (42~ A 16 Ra I/ a _,2~- a, ( a,27 + a,) and it is the same in the other three cases, i.e. R. instead of A, Card 5/7 33774 B/108/62/017/001/001/007 Ideal predictional reception of D271/D304 etc. Finally an expression is found for the error probability of any signal in any interval. It is concluded that prediction methods are effective when there is a strong correlation between signal and interference components in adjacent intervals, and'the error proba- bility is then 2.5 times smaller than for the conventional frequen- + cy shift telegraphy. As the correlation weakens, the advantages gra- dually disappear until, with small correlation values, phase-tele- graphy is leas reliable than frequency shift telegraphy; predictio- nal phase telegraphy has a certain intrinsic error probability inde- pendent of interi:erence. A preliminary and approximate evaluation of analytical results on the basis of available experimental data shows that predictional phase telegraphy may produce good results when T = 3 msec, but tb,~-rb is no hope for it when T =20 maec.

The V. M. Bogachev et al. method of transmitter calculation ("Calculation of stages of transistorized transmitters. " MEL. 1964) based on a harmonic analysis of base Card I I Z 621.396.6.029.55(6Z):6ZI.382 AGG NR: AT7004346 and collector currents is regarded as the most accurate (differs from experimental data by Z5-30'fo) and reliable. A common-emitter grounded -collecto r circuit is the simplest and most convenient for practical use. Effective heat removal, such as described by K. H. McPhee (Electronics, 1961, v. 34, no. 18, pp. 76-78) largely determines the success of using high-power transistors. These transistors were tested in a single -transistor oscillator at frequencies between 9 and 150 Mc: Soviet, KTOOZA, type I experimental, type 2 experimental, type 3 experimental; USA, 3TX-004 Clevite, ZN2947 Motorola, ZN3632 RCA. Further, several 3-stage transistorized transmitters were developed and tested with these results: New Sov-iet transistors permit constructing transmitters up to 10 w at 100 Mc, or 30 w at 50 Mc, or 40 w at 30 Mc, or 100 w at 20 Mc; in all cases, the output stage has one transistor, and the efficiency is fairly high.

PMTF, 1963, No. 4) presented results of experimental investigations into spherical detonation waves fn loessial soil of undis- turbed structare and natural humidity. The pre if-a-ri-teTe-presents the results of analogous Investigations performed In the same goils, but with a different humidity (w = 19-2 1% and 6 = 1. 34- 1. 38 g/ern3; where w to the humidity by weight, and 6 is the specific weight of the skeleton of the soil). Some of the experiments; were performed in Card 1/2 L .7 ACC NR: AP6009064 3 a soil with a disturbed structure (6 = 1. 30- 1. 34 g/cm with w = 19-21%). An analysis of the results obtained shows that with Increasing humidity the coefficients of internali friction and cohesion decrease. A disturbance of the structure of the soil leads to a more abrupt decrease in these coefficients. R is noted that during both the application and the removal of the load, the state of plasticity coincides.

In the first course the students are taught the cold machining of metals and the assembling of radios. In the training workshops they learn the fitter's trade. The article then deals in detail with the necessity of early training in radio repair and the various operations which the students are taught. The next section cf the article describes student practical laboratory work, where methods adopted by the Moscow Physico-Technical Institute and the Moscow institute of Fnergetico are applied, The last section quotes a few examplou from the Faculty's practice showing how practical skill is )btained by the utudents in connect- ion with their course-examination. The experience of the Card 112 Radio-Technical Faculty proves that the students can be The Students Gain Production Skilla 3-3-16/40 taught practical skill at all stages of training.
