Title: Stereo demodulating circuit
Inventor: KIMURA SHIGENOBU
IPC: H04B1/16
Filed: 1981-06-30
Abstract: PURPOSE:To reduce crosstalk components, by multiplying the rectangular wave signals which contain a DC component set to a stereo composite signal and are synchronized with the subcarrier frequency. CONSTITUTION:A stereo composite signal Ei is applied to the operational amplifiers OP1 and OP2, and at the same time a clock signal of 38kHz is applied to the analog switches S2 and S3.
