ABSTRACT:
A blanking signal is generated in a television receiver when a channel change selection is made. The blanking signal is low-pass filtered and thereafter controls the muting of the audio channel. Muting and un-muting are thus accomplished gradually, without audio disturbance. The tuning voltage is allowed to change to the new value required only after a delay period following the start of the blanking signal. Muting is therefore substantially complete before tuning transients can occur.
