Abstract

PURPOSE: To suppress the beat noise with a simple adjustment by supplying the color video signal into the gate of the 1st FET and also supplying the FE aural signal into the gate of the 2nd FET after cutting off the DC component to lead out the mixture output.
CONSTITUTION: Color video signal Sv containing the color signal modulated by the subcarrier is supplied into the gate of FETQ1 after the DC reproduction via 1st capacitor C1 and diode D. At the same time, the aural signal is changed into FM aural signal Sa through the FM process via the carrier of 4.5MHz and then supplied into the gate of FETQ2 via capacitor C2 in order to lead out the mixture output through drains of FETsQ1 and Q2. As a result, the beat noise can be suppressed with a simple adjustment.
