Abstract
A hybrid TV frequency modulation feedback loop (FMFB) remote volume control includes an RF input and an intercarrier audio detector circuit connected thereto to provide a baseband audio signal. An amplitude control is provided for the audio signal. There are means for using the video carrier at the RF input to provide a signal representative of common mode spurious deviation (CMSD). There are circuit means for combining the common mode spurious deviation signal the amplitude controlled baseband audio signal, from the intercarrier audio detector and for providing an aural carrier signal having common mode spurious deviation and amplitude controlled audio.
