| Abstract: | The frequency-modulating transmitter with multiple pre-placed frequency points utilizes MOSFET with high efficiency as the key element, and it is implemented by using circuits of signal input, audio frequency amplification, the carrier generator, the frequency modulation and the frequency modulation transmission. This transmitter can be used in areas such as micro-radio stations, internet lecturing and reporting, baby and elderly care and so on. A practical test shows that it has some practicability in application. |
