Abstract

PURPOSE: To make it possible to transmit definitely even two signals or more superposed by attaining the time-division transmission of input signals at the transmission side.
CONSTITUTION: Input signal 1 is transmitted for time (t1) and after transmission is out of operation for time (t2), input signal 2 is transmitted for (t1). In the same way, input signal (n) is transmitted for time (t1) and after transmission is out of operation for time (t2), input signal 1 is transmitted again. If an input signal arrives at this time, combination circuit 1 forms the constitution of nCr and oscillators 2 oscillate at the (r)-number frequencies; and transmitting band-pass filters 3 remove unneeded side-band signals and signals from filters are coupled through and coupling 4 and amplified before being transmitted to transmission line 9. The received signal is passed through receiving amplifier 5 and reveiving band-pass filters 6 and detected by detector 7. Then, the detected signals are tested by test circuit 8 in terms of nCr and signals which have passed through the test are transmitted.
