Function
Equivalent circuit
This filter is used to hold the FM detector output DC voltage
fixed.
Normally, a 1-F electrolytic capacitor should be used.
The value of this capacitor can be increased to improve the
low band (around 50 Hz) frequency characteristics.

FM filter
Audio FM detector output
This is an emitter follower output with a 200-
resistor
inserted in series.
Stereo applications
Some applications may find that the stereo decoder input has
a low input impedance, and that the left and right signals are
distorted, i.e. that the stereo characteristics are degraded. If
that is a problem, add the resistor R1 shown in the figure
between pin 24 and ground.
R1
≥ 5.1 k
Mono applications
Use an external deemphasis circuit with the following time
constant:
t = 2RC
