Abstract
PURPOSE: To simplify channel-selecting operation by stopping the automatic scanning of a received frequency automatically when a receiver is tuned to radio waves from a certain broadcast station.
CONSTITUTION: To programmable counter 17, a channel-selective signal is inputted from either programmable board 24 or autoscanner 25. Through manual operation, board 24 sets a channel frequency to be recieved ang generates and outputs a code signal as the channel-selective signal. At the timing of a frequency much lower than that a counter 17, scanner 25 outputs as the channel-selective signal a code signal whose numeral varies at any time within the numeral range equivalent to the received-frequency band, and scans the preset value of counter 17 at certain timing by this numeral variation. Then, the scanning is stopped when a FM carrier more than a certain level is inputted stably.
