Abstract
PURPOSE: To automatize preset channel selection by storing successively tuning voltage information and band information of respective channels selected automatically with digital signals.
CONSTITUTION: At a preset channel selection operation time, an information counter counts clock pulses by a search start signal from start.stop circuit 9, and the counted value is inputted to D/A converter 12 and is converted to a DC analogue voltage and is applied to electronic tuning tuner 2. When a television radio wave is received at the best tuning point, the search start signal is stopped, and memory circuit 16 stores tuning voltage information and band information digitally in the memory cell of designated addresses and stores skip signals in an idle memory. Then, when the skip signal is detected in a normal channel selection, address counter 17 is shifted to skip addresses.
