Abstract
A pulse waveform generator circuit which is suitable for integrated circuit construction is disclosed. The invention functions as a square-wave generator for switching the outputs of tape scanning heads in a video tape recorder. The circuit includes: a first pulse generator for producing a first pulse signal with a predetermined pulse width and a second pulse generator which produces a second pulse signal with predetermined pulse width between two of the adjacent first pulse signals; a flip-flop circuit set by the first pulse signal at its leading edge and reset by the second pulse signal at its leading edge; a first logic circuit which is supplied with an output signal from the flip-flop circuit and the second pulse signal to produce a third pulse signal which is held in one state from the trailing edge of the second pulse signal to the leading edge of the first pulse signal; and a second logic circuit which is supplied with the third and first pulse signals to produce a desired pulse signal. In this case, the desired pulse signal is reversed at each of the trailing edges of the first and second pulse signals.
