ABSTRACT:
A pulse generator includes a transducer such as a resolver coupled to a driven body for converting a mechanical motion thereof to a phase-modulated signal, an excitation signal generator for supplying an excitation signal as a carrier of the phase-modulated signal to the transducer, a clock pulse generator for generating a train of clock pulses, a waveform shaping circuit for shaping the waveform of the phase-modulated signal issued from the transducer, a counter for receiving the clock pulses to form a content of count representing a time interval by which the output from the waveform shaping circuit being in a high or low logical state is longer or shorter than the corresponding period of the excitation signal, a count pulse generator for generating count pulses, a gate circuit for allowing the count pulses to enter the counter until the counter having contents of count corresponding to the time interval is initialized while the output from the waveform shaping means is in its a succeeding low or high logical state, and an output gate circuit for issuing out the count pulses counted by the counter to issue out as a serial train of pulses.
