Abstract

See full text

A method and a device for controlling and removing narrow pulses in a clock waveform using a delay function are disclosed. A circuit device includes three circuits wherein the first circuit is capable of generating an edge trigger signal in response to a waveform of an input signal and a waveform of an output signal. While the second circuit facilitates removing a narrow pulse from the waveform of the input signal, the third circuit is capable of generating a delayed output waveform having pulses greater than a predefined minimal pulse width. In one embodiment, the first, second, and third circuits are an exclusive OR gate, a delay circuit, and a D flip-flop, respectively.
