TRANSCEIVER FOR HALF-DUPLEX COMMUNICATION Russian patent published in 1996 - IPC

FIELD: radio engineering, automation and computer engineering. SUBSTANCE: device generates radio signals using clock pulses, reverse clock pulses, and divider. When radio signals are received, pulse bursts are generated. They are used for detection of envelope. Demodulator generates differential frequency which is measured in pulse counter by counting pulses, which number is proportional to differential frequency. Voice signal at output is generated using these data. EFFECT: increased functional capabilities. 1 dwg
