УСТРОЙСТВО РАДИОКАНАЛА СВЯЗИ ДЛЯ ПЕРЕДАЧИ И ПРИЕМА ЦИФРОВОЙ ИНФОРМАЦИИ

摘要

FIELD: digital data transfer over radio lines; radiotelemetry and computer data exchange systems. ^ SUBSTANCE: opposite-polarity pulse signals are shaped on receiving end of device upon conversion of input signal levels, converted signals being close to ball-shaped ones; positive-polarity signals are fixed to rise time of input signal and negative-polarity ones, to its fall time. Ball-shaped opposing-polarity signals arrive at frequency modulator affording appropriate deviation of radiated signal. Ball shape of signals provides for minimizing signal spectrum width at permitted spectrum width of radiated signals. On sending end of device levels of opposing-polarity signals received are compared and output signals are generated which enables data transfer at any speed permitted by State Standard. ^ EFFECT: enlarged speed range for data transfer. ^ 1 cl, 3 dwg
