In addition to the known compounds CdSb (stable) and Cd 3Sb2 (metastable), they detected Cd 4Sb31 (simil &r to Zn4 Sb 3) in the system Cd-Sb. They studied this system thermographically and by X-rays, and examined its miorostructure and microhardneas. ;They studied the electrical conductivity and the thermo-emf on cadmium all Ioys with a maximum of 5-10-3% impurities, and antimony of the type Cy 000 (SuOOO). KAO (KdO cadmium and '_-j00(Su00) antimony were used foi other determinations. Three series of alloys were heated to 6500C in evacuated (to 7-10-3 mm Hg) Pyrex ampuls, and shaken at 500-5500C for 5 hro Series 1 was cooled in the air, series 2 together with the furnace, series 3 was annealed between 250 and 4200C for one week.

G., Active Member, VWORiB Title : Comparative evaluation of communication chani 'iols for different systems modulation by their transmission capacity Periodical : Radiotechnika, 10, 58-66, Jun.55 Abstract The article discusses the fundamental relations of the statistical theory of communication. On the basis of this theory formulas are derived for calculation of the transmission c~apacity of two follow- ing cases: when the signal is limited in its amplitude and when the signal is limited in its mean power. A comparison with respect to their relative transmission efficiencies Is made of the follow-: Ing systems of signal modulation: single-sidebanil, azuplitude)~ fre- quency, pulse time, pulse width and pulsecode. Tramission capacity of a channel depends on the statistical wave spectrum of the signal and the intensity of noise. For certain conditions, frequency modu- lation and code modulation have greater trammission capacity than the other modulation systems investigated. The author thanks I. Ye.

The quantitative evaluation of the noise-IMMUMIty under these conditions is based on the statistical parameters of the frequency fluctuation and it can be assumed approximately that these fluctuations C = W 0 - W can be described by the normal probability density distribution-, 34268 S/142/61/004/005/ol4/m4 Noise immunity of ....
