ABSTRACT:
A monitoring apparatus which is operable during muting, even though it relies on audio to monitor program signals transmitted by broadcast sources. The monitoring is performed by transmitting a combined signal derived by adding a code to an audio program signal. During muting, the audio is inhibited by actuating a switch. However, the code is separated from the combined signal and routed so as to bypass the switch in order to enable the monitoring to continue.
