Abstract

디지탈방식에 의한 펄스발생장치가 개시된다.Disclosed is a pulse generator by a digital method.

본 발명의 디지탈 펄스발생장치는 트리거신호에 의해 구동되어 클럭신호를 계수하는 계수수단; 계수수단의 계수값을 입력하여 그에 인가된 제1검출값과 비교하고, 그 결과를 제1판정신호로서 출력하는 제1비교수단; 계수수단의 계수값을 입력하여 그에 인가된 제2검출값과 비교하고, 그 결과를 제2판정신호로서 출력하는 제2비교수단; 그리고 제1비교수단에서의 제1판정신호에 의해 그의 출력상태가 반전하고 제2비교수단에서의 제2판정신호에 의해 원래의 상태를 회복하는 펄스출력수단을 포함한다.A digital pulse generator according to the present invention includes counting means driven by a trigger signal to count a clock signal; First comparing means for inputting a count value of the counting means, comparing the count value with the first detection value applied thereto, and outputting the result as a first determination signal; Second comparing means for inputting a count value of the counting means, comparing it with a second detection value applied thereto, and outputting the result as a second determination signal; And a pulse output means for inverting its output state by the first determination signal in the first comparison means and restoring the original state by the second determination signal in the second comparison means.

본 발명에 의한 디지탈 펄스발생장치는 브리거펄스에 의해 구동되는 카운터의 계수값을 펄스의 기립시점과 하강시점을 나타내는 소정의 검출값과 비교하고 그 결과에 의해 펄스를 발생토록 함으로써 발생되는 펄스의 폭을 자유로이 설정할 수 있는 장점을 갖는다.The digital pulse generator according to the present invention compares the count value of a counter driven by a brigger pulse with a predetermined detection value indicating a standing time and a falling time of the pulse, and generates a pulse accordingly. The advantage is that the width can be set freely.
