技術說明

一種頻移鍵控解調裝置，包含一轉導電路、一延遲電路、及一混波電路，該轉導電路接收一對差動輸入電壓信號，該延遲單元產生具有相關該對差動輸入電壓信號的調變相位的一對差動中間信號，該混波電路將該對差動輸入電壓信號及該對差動中間信號進行混波，以產生具有該對差動輸入電壓信號與該對差動中間信號之乘積成分的一對差動輸出電壓信號，以實現該頻移鍵控解調功能，該混波電路、該延遲電路、及該轉導電路依序串聯於一電源電壓及一接地點之間以達到功率消耗較小的優點。 A frequency shift keying demodulating means comprises a switch electrically conductive path, a delay circuit, and a mixed-wave circuit, the switch circuit receiving a pair of conductive voltage differential input signal, the delay unit generates the differential input voltage on the relevant tune disguised bit of a pair of differential intermediate signal signal, the mixed wave circuit the differential input voltage signal and the pair of differential intermediate signal wave mixing to produce a differential input voltage signal that the pair of difference a pair of differential output voltage signal of the intermediate signal component of motion of the product, in order to achieve the FSK demodulation, the mixed wave circuit, the delay circuit, and the switch in series with a conducting path sequentially supply voltage and a ground between locations in order to achieve the advantages of small power consumption.
