DEVICE FOR INTERFACE BETWEEN COMPUTER AND COMMUNICATION CHANNEL Russian patent published in 1995 - IPC

FIELD: computer engineering. SUBSTANCE: transmitting part of device has flip-flop, master oscillator, pulse distributor, interface unit, transmitting unit and unit for generation of interrupt pulses. Receiving part of device has pulse generator, clock synchronization unit, interface unit, receiving unit, master oscillator, unit for generation of interrupt signals, control unit, memory unit, signal selector. Device provides possibility to analyze rate of pulse edges in signal which is read from output radio receiver of communication channel. Transmitted message is separated by constant level signals which duration exceeds possible maximal duration of constant level signal in noise sequence of random signals having equal probability. The latter duration is longer than maximal duration of constant level signal in message encoded by correlation code. EFFECT: increased stability to noise, simplified hardware. 13 dwg, 1 tbl
