Receiver

Abstract

Abstract PURPOSE:To make easy the selection of the reception of broadcast, through the display of electromagnetic waves during broadcasting, by providing the memory unit storing a plurality of information which indicates the state of reception collected from the reception function section and CRT and control circuit displaying this information. CONSTITUTION:With the application of power supply in the receiver, the CPU10 produces a signal controlling the varactor diodes 12-14 in the high frequency amplification stage 2, mixing circuit 3 and local oscillator 4 via the input and output adaptor 9 according to the program stored in ROM, to change the capacity of the diodes, and frequency sweep is made over the entire band of reception. The reception state such as the strength of electric field to frequency, whether or not turning point, and whether or not stereo is detected with this sweep, and the information is stored to RAM of the CPU10. The strength of electric field to each reception frequency of this reception state is displayed on the CRT11 as a bar graph over the entire band, and the receiver is set taking consideration into the information displayed for desired reception.
