ABSTRACT:
A pulse duration measuring apparatus generates a clock signal in the form of a clock pulse train having a period(T) and delays the clock signal and provides N-1 number of delayed clock signals, each of the delayed clock signals delayed by a delay time((T/N)*i), N being a positive integer and i being 1 to N-1 and counts the number of the clock pulses contained in the clock signal and each of the delayed clock signals, respectively, during the duration(Y) of the input pulse signal(I) and providing the count values. A pulse duration measuring apparatus detects a maximum counted value(n) among the counted values provided from the counting means and calculates the duration(Y) of the input pulse signal(I) based on the maximum count value(n).
