Abstract

The invention relates to a device for automatically recording listening behavior of a frequency and amplitude modulating broadcast, in particular to a cassette automatic recorder for the listening behavior of the frequency and amplitude modulating broadcast, wherein a liquid crystal display screen of the cassette automatic recorder is connected with a microprocessor; a key matrix is connected with the microprocessor; a radio receiving unit is connected with the microprocessor and a power amplifier which is connected with a loudspeaker; a receiving antenna is connected with the radio receiving unit; a real-time clock is connected with the microprocessor; and a cassette is connected with the microprocessor and a card file. The microprocessor transmits frequency information and time information searched by the real-time clock to the card file for recording during broadcasting. The invention can record and store the listened frequency and time of a broadcast station in real time, automatically record data to special cards, periodically collect a plurality of cards for investigating the rate of audience and has simple and convenient use, high efficiency, economy and reasonability.

Description

technical field [0001] The present invention relates to a device for automatically recording the listening behavior of FM and AM broadcasting, in particular to an FM and AM broadcasting that can automatically record data on a special card, collect many cards regularly to investigate the listening rate Listen to the behavioral cassette autorecorder. Background technique [0002] FM radio and AM radio are popular media for disseminating information. The content of a radio program directly determines the degree of attraction to the audience, and the listening rate is an important indicator for evaluating the number of audiences. The conclusion of the listening rate survey is an important means of selecting media and estimating the effect of advertisements. At present, various survey agencies at home and abroad mostly use questionnaires to investigate radio listening behaviors, that is, investigators go to households to ask and fill in forms, which is inefficient, high in cost,...
