3.4.1.2.1.2. Video + PCM Input Signals
 Next figure shows an IF Modulator set to Video + PCM mode for FM or PM modulation of
the IF carrier by a low bandwidth signal (low bandwidth TCU or RAU) and a high bandwidth
PCM signal (high bandwidth TMS).
 IF modulation is limited to PM and FM.
 Matched filters are not available.
