Abstract
PURPOSE: To obtain a constant measured value without any influence of the time of the rise and fall of a video signal by measuring the width and interval of a pulse of a level a certain value lower than that of the video signal as to a radar, etc.
CONSTITUTION: A video signal is quantized by multistage slicing circuit 12, each quantized signal of which is differentiated at its rise and fall by video edge detecting circuit 13 with basic clock 9 and leading-edge signal 15 and trailing-edge signal 16 are counted at 14 respectively. Then, clock 9 is counted by timer 17 and time signal 17a is supplied to rise-time register group 18 and fall-time register 19. On the base of outputs of circuits 12W14, control circuit 20 supplies control signal 20a to selecting circuit 23, which selects a fixed time from register group 18 and supplies its signal to pulse-interval calculating-outputting circuit 24 and pulse-width calculating circuit 25. Circuit 24 performs arithmetic between fixed times to find pulse interval 11 and circuit 25 finds pulse width 10 by operating the time of register 19.
