Analog common frequency duplex communication system

Номер: CN0001102020A
Автор: DONGHAI LU, LU DONGHAI
Принадлежит:

The duplex communication system mainly features that analog signals has PAM or PWM modulated and synchronous time-sharing duplex is realized without synchronizing signal. The sender transmitts PAM or PWM signals in fixed frequency and receiver uses the leading or back edge of these signals as reference and returns the pulses at proper time. The delay transform of return pulses is set up. Its advantage is low cost.
