ABSTRACT:
An apparatus for correcting wave distortion. An input signal is supplied to a delay circuit, the input signal being so modulated that an accumulated value of a time interval from its leading edge to its trailing edge equals another accumulated value of another time interval from a trailing edge to a leading edge. The delay circuit generates plural successively delayed outputs, each of which has a certain time delay shorter than the time interval. A selector selects a plurality of delayed signals among the plural delayed outputs. A synthesizer synthesizes a plurality of delayed signals so that a synthesized signal can be obtained by correcting at least one of the time interval and the another time interval through the certain time delay. A detector detects a difference between a time interval from a leading edge to a trailing edge and another time interval from a trailing edge to a leading edge of the synthesized signal out of the synthesizer. A generator generates a control signal which controls, based on a detected output by the detector, the selecting operation and the synthesizing operation so as to accumulate a value of a time interval from a leading edge to a trailing edge of the synthesized signal equal to another accumulated value of another time interval from a trailing edge to a leading edge of the synthesized signal.
