5-1-9 AGC Stability Circuit

5-1-10 Post Filter

5-1-11 Center Voltage Generation Circuit

The gain is adjusted by AGC Block with the function of maintainning the definite RF peak to peak level,
after the operation of RF envelop detection and comparing with reference voltage.
RFO level is kept stable in 1Vp-p, and input to EFM Slice.

The adjustment of audio output gain and the integration of possible de-emphasis output are executed by
the low pass filter. If the control by MUTE signal from micom exist, and when input signal absent, two
channel of right and left is builted in.

The Center Voltage is generated by using resistor dividing voltage.
