FIELD: information transmission and reception equipment. SUBSTANCE: in agreement with procedure sequence of digital readings of information is converted at transmitting side to analog signal with the help of sampling function of the form sin•(cos(x/n)-1)/2sin(x/n) where x = 2πFup, Fup is upper frequency in spectrum of transmitted analog signal and n is integral number equal to number of frequency components used in spectrum of analog signal. Analog signal so formed is sent to communication line. At receiving side initial sequence of digital readings is restored by means of mentioned sampling function. Procedure is realized with the aid of corresponding converter of sequence of digital readings of information to analog signal. EFFECT: reduced value of distortions in process of transmission of discrete digital readings of information. 2 cl, 3 dwg
