Title: Pulse width detector
Inventor: NAITOU HATSUHIKO
IPC: G01R29/02
Filed: 1979-03-23
Abstract: PURPOSE: To enable to detect the pulse width with a simple constitution and high accuracy, by counting the clock pulse on the pulse width and generating the marker pulse when the output level is in agreement with the reference level.  
     CONSTITUTION: When the signal in which pulse width is changed is inputted to the gate AND from the terminal in, the pulse from the clock pulse genertor CLG is inputted to the counter by the number corresponding to the pulse width. The number of clock pulses N 1  corresponding to the set pulse width t 1  and the digital number N 1  of the same number are inputted to the adder AD and held at the register REG. The output of the counter and the reference level of REG are compared at the digital comparator DC, and the marker pulse P t1  is outputted via the multi-OM when in agreement. The output pulse N 1  of REG is inputted to the adder AD into being 2N 1  and stored in REG. When the pulse P 1  is inputted to the reference level alteration circuit TC, 2N 1  is outputted from REG to DC, the output of AD is 3N 1  and marker pulse is outputted every time when the input pulse width is a multiple of the reference pulse width.
