Abstract

PURPOSE: To enable to preset automaticall all the broadcast stations receptionable to the most suited tuning point, by sequentially and automatically memorizing the reception waves after selection channel switch, in TV receivers.
CONSTITUTION: The switch corresponding to the broadcast station preset at first is selected among the channel selection switch 9, and it is set in the address memory 7 corresponding to it with the counter 11 via the encoder 10. Further, when the preset start switch 12 is turned on, the output of the pulse generator 5 is counted 3 via the gate 4 and when the tuner 1 reaches the most suited tuning point via the A/D converter 2, the gate 4 is turned off with the output of the tuning detection 6. Further, the memory 7 fetches the content of the counter 3 via the circuit 8 and after that, the address is renewed. Further, the output of the crcuit 8 opens the gate 4, and similarly, the next broadcast station is memorized in the memory 7 resulting that the broadcast station corresponding to the band is preset
