3.4
Figure 3-16 illustrates an example FM application
circuit.
3.4.1
FM demodulation is performed in the same manner as
described in the FSK section above.
3.4.2
The internal operational amplifier is configured as an
active low-pass filter.
FM audio is typically de-emphasized. It is recom-
mended that de-emphasis circuitry be connected at the
output of the operational amplifier rather than the
output of the detector.
