IF Amplifier Input
IF Decoupling. External 0.1 F
capacitors connected to V CC .
IF Amplifier Output Signal level is
typically 300 mVpp.
Quadrature Detector Input. Signal
level is typically 150 mVpp.
Recovered Audio. This is a composite
FM demodulated output having signal
and carrier components. Typical level
is 800 mVpp.
The filtered recovered audio has the
carrier signal removed and is typically
500 mVpp.
