Abstract

PURPOSE:To elevate an economical property by using a digital transmission line, and executing transmission by the pulse width modulation system. CONSTITUTION:An analog signal is converted a pulse width modulation signal by the modulators 8a, 8b, its parallel-series conversion is executed by the multiplexer 2b, and the signal is sent out to the transmission line 4b by the digital transmitter 3b. And, the signal which has been sent is received by the digital receiver 5b, its series-parallel conversion is executed by the demultiplexing circuit 6b, and the pulse width modulation signal is demodulated to its original analog signal by the demodulators 9a, 9b.
