发明名称 FSK signal demodulator
摘要 An FSK signal demodulator for demodulating digital data from a frequency shift keying signal. A timing clock for the digital data is extracted from the FSK signal, and a sampling circuit samples the FSK signal by means of a clock having a frequency which is almost equal to one frequency of the FSK signal or which is almost equal to an integral multiple of that fequency.
