Correction method and correction means

The present invention provides an apparatus and method for correcting correction. Correcting means comprises a correction circuit and detecting circuit. The relationship between the edges of the multiplex signal generated by the detection circuit detecting multiple sources, to produce a detection result, wherein the at least one edge of the plurality of edge is a falling edge. The correction circuit is coupled to the detection circuit, and based on the detection result of the correction to the at least one signal source. Correction method comprising the steps of: a relationship between the edges of the multiplex signal generated by detecting multiple sources, to produce a detection result, wherein the plurality of edges at least one edge of a falling edge; and a correction result according to correcting the at least one signal source of multiple signal sources. Correction apparatus and related method of the present invention provides a correction may correct distortion signal source to undesirable effects caused by the transmitted signal is compensated.
