Abstract

PURPOSE:To obtain a waveform monitoring screen by simple circuit constitution by projecting variations of the prescribed value of a video signal as a bright point in every horizontal retracing. CONSTITUTION:A video signal V arriving at an input terminal 1 is supplied to a diode 17 for white level peak value detection to supply the peak of its white level to a capacitor 18, which is charged in the off period of a switch 4 operated with a clamp pulse (c) from an input terminal 5 and also discharged on its on period to generate a signal d3. The signal d3 is compared by a comparator 19 with a horizontal deflecting pulse d2 from an input terminal 12 to generate a signal (h). A differentiating circuit 20 generates a signal (i) which has pulses only at rises of the signal (h). The signal (i) is supplied to a blanking pulse amplifier 21 to generate a signal (j), which is supplied to a video amplifier 22 to obtain a signal (k) from a terminal 23. At the timing of this (k), a bright point appears.
