DIGITAL FUNDAMENTAL PRP ANALYZER FOR PULSE TRAIN SIGNALS

A pulse-repetition-period analyzer comprising binary converter means for converting an input waveform into a series of equal-amplitude binary pulses, variable-length shift register means for sorting the pulses into a series of successive pulse trains ordered according to their pulse repetition periods, shift register means for rejecting from each pulse train any pulses constituting a harmonic rather than a fundamental signal at the input, weighted integrator means for individually integrating said fundamental pulse trains and time-delay control means for controlling the delay (or length) of the variable-length shift register and synchronizing the operation of the other components of the circuit.
