Abstract
PURPOSE: To ensure the channel selection display with omission of the complicated working due to the mechanical display of the channel selection by providing each display element which glows when a synchronization is obtained with the electric wave of each broadcast station and without installing the complicated electronic circuit.
CONSTITUTION: The output of local oscillator 2 constituting the radio receiver is drawn out to be sent to prescaler 7, and then supplied to central information process circuit 8 after division into the prescribed frequency. Circuit 8 consists of the memory circuit which can memorize freely the fixed frequency of each broadcast station plus the selector which memorizes the signals from prescaler 7 and then compares the output of the memorized signals to deliver the drive signals corresponding to LED10a∼10g functioning as the display elements. Then the output of circuit 8 is supplied to LED10a∼10g via LED drive circuit 9. And when the coincidence is obtained between the frequency divided by prescaler 7 and the frequency of each broadcast memorized in circuit 8, LED10a∼10g are selected for display.
