Abstract

PURPOSE:To realize the transmission of the signal information equal to a received signal through a simple and easy-to-handle device, by controlling both the received signal and the signal delayed by a certain time with the voltage signal corresponding to the angle frequency components of the corresponding sine and cosine signals. CONSTITUTION:The tau-time delayed signal and the received signal which are divided through a distributor 13 into two parts receive a division from a dividers 19 and 20 via a phase discriminating circuit 15 plus diodes D1-D4, etc. as well as via a diode D5. The outputs of the dividers 19 and 20 are supplied to a converter 21. Then an exciter 22 and an oscillator 23 to deliver a repeater signal. In this case, the converter 21 converts the output into the voltage E in accordance with the degree of variation of the angle frequency omegatau to be supplied and then delivers it. The output of this conversion drives the oscillator 23 via the exciter 22. Thus the output corresponding to the above-mentioned received signal, i.e., the frequency component equal to the frequency component of the received signal is delivered to be transmitted through an antenna 11 and via a transmission-reception switch 12.
