Abstract

FIELD: electrical communications; telephone communication. SUBSTANCE: device has on sending end: comparator, four-bit shift register, one(zero) density analyzer, syllable filter, compander, amplitude-pulse modulator, and two-section integrating filter; it also has digital error channel, on receiving end it has: four-bit shift register, one(zero) density analyzer, syllable filter, compander, amplitude-pulse modulator, two-section integrating filter, and low-frequency filter. In addition, device is provided with transmitted digital information validity analyzer whose transmitter has switch, pulse generator, sync pulse generator, and control circuit, and its receiver has switch, comparison circuit, error counter, digital-to-analog converter, sync pulse detector, and control circuit, as well as adjustable amplifier. EFFECT: improved channel and acoustic noise immunity. 2 cl, 3 dwg
