ABSTRACT:
A TV remote volume control includes an RF input for receiving the video modulated RF carrier and the audio modulated RF carrier, both with common mode spurious deviation. The audio modulated RF carrier is demodulated to provide a baseband audio signal without common mode spurious deviation. The video modulated RF carrier is used to provide a video RF carrier signal with common mode spurious deviation. The baseband audio is volume controlled and the volume controlled baseband audio is then used to provide an audio modulated IF carrier. The volume controlled audio modulated IF carrier is combined with the video carrier with common mode spurious deviation to provide a volume controlled audio modulated RF carrier with common mode spurious deviation.
