Patent ID: 8437377

Claim:
A pulse generator comprising: a filter that limits a band of an input signal; and a pulse generator that generates a plurality of pulses which are sequentially delayed one after another by a time period (τ) equal to a reciprocal of a center frequency of the band of the filter, and inputting the plurality of pulses to the filter, wherein the pulse generator includes: a logical product circuit that takes a logical product of either: a clock signal and a signal formed by delaying the clock signal by the time period (τ) and by inverting the logic of the delayed clock signal, or a clock signal and a signal formed by inverting an output of the logical product circuit and by delaying the inverted output by the time period (τ); and an exclusive logical sum circuit that takes an exclusive logical sum of an output of the logical product circuit and a signal formed by delaying the output of the logical product circuit by a given time period.
