ABSTRACT:
A signal wave control circuit includes a comparator having an input terminal for receiving an input signal, another input terminal for receiving a reference level signal and an output terminal producing an output signal having positive and negative portions corresponding to the input signal, a detector for detecting the maximum or minimum transition interval included in the output signal and for producing a detected signal, a hold circuit for holding the detected signal, and a control circuit for producing the reference level signal, whereby the interval of the positive portion of the output signal and the interval of the negative portion of the output signal become equal to each other.
