FIGURE 15. Monaural Cascade Connection
FM STEREO
When using the DNR system with FM stereo as the audio
source, it is important to eliminate the ultrasonic frequencies
that accompany the audio. If the radio has a multiplex filter
to remove the ultrasonics there will be no problem.
This filtering can be done at the output of the demodulator,
before the DNR system, or in the DNR system control path.
Standard audio multiplex filters are available for use at the
output of the demodulator from several filter companies.
Figure 16 shows the additional components L1, C15 and
C16 that are added to the control path for FM stereo appli-
cations. The coil must be tuned to 19 kHz, the FM pilot
frequency.
