摘 要: 根据定时式脉冲鉴频原理,本文给出一种适用于计算机无线电通信的调制解调器,该电路用TTL计数器和译码器产生定时信号,实现频移键控调制和解调,其数据传送速率为1200bps。 This paper gives one MODEM that is applicable for computer radio communication according to the principle of timing pulse frequency discrimination. Counters and decoders of TTL are used in the circuit to produce timing signal, to achieve modulation and demodulation of frequency-shift keying. The data transfer rate of the MODEM is 1200 bps.
