Abstract

PURPOSE: To improve the operation by automatizing preset channel selection by storing automatically tuning voltages of respective channels selected automatically by a TV receiver in sequence.
CONSTITUTION: A signal from circuit 9 by a search start command causes tuning- voltage generating circuit 10 to make a sweep and its output tuning voltage is supplied to tuner 2 via memory 11. During the reception of a TV radio wave, if a search stop signal is outputted from noise skip circuit 13, circuit 10 is made to stop its operation temporarily. During this, signal discriminating circuit 12 discriminates a received signal and when it is normal, and the tuning voltage from circuit 10 is stored in memory 11. In this way, tuning voltages of respective chnnels are stored in respective memories in sequence and preset channel selection is done
