Abstract

PURPOSE:To facilitate a channel selection and at the same time prevent the misoperation, by giving an announcement of the name of the broadcast station by the coincidence signal between the reception frequency and the memory frequency in the memory. CONSTITUTION:The memory MM of RAM constitution contains the region MA to store the frequency of the broadcast station and the region MB to store the name of the broadcast station in the form of the binary code. And the writing is performed by the address control part AC, the input control circuit IC1 in the region MA and the input control circuit IC2 to the region MB each. The key unit KU contains the alphabet keys and the figure keys, and the name of the desired broadcast station is preset to the memory MM through the key encoding circuit EC. The coincidence circuit J compares the value of the reception frequency memory circuit DB with the frequency of the region MA in the memory MM and then delivers the detection signal when a coincidence is obtained. The aural output control circuit OC delivers the contents of the region MB to the aural compounding circuit VC according to the coincidence signal and also performs a control of the aural output. The display unit DSP2 for the name of broadcast consists of the dot matrix display unit and is driven by the display driving circuit DSC2 for display.
