Filed: 1980-10-23
Abstract: PURPOSE:To demodulate a frequency with a simple constitution and without adjustment, by operating AND between a signal which is obtained by delaying the signal, and the original signal and by integrating the output. CONSTITUTION:The signal from an intermediate frequency amplifying circuit is inputted to one input terminal of an AND circuit G1 through a delay circuit 10. The signal is inputted directly to the other input terminal. The duty ratio of the pulse in the output of the AND circuit G1 is low if the frequency of the signal is high, but a pulse of a high duty ratio is outputted if the frequency of the signal is low. This pulse is integrated by an integral network 11 to obtain a demodulation signal. A circuit such as an NAND circuit to satisfy conditions of the product can be used instead of the AND circuit G1.
