Patent ID: 7515613

Claim:
A sending circuit comprising: an encoder for generating a transmission signal by encoding an input signal that is inputted from outside; wherein the transmission signal is outputted to a plurality of signal transmission lines, while switching a value of the transmission signal at every elementary period, which is a preset period; wherein the encoder encodes the input signal such that a logic level of a signal outputted to at least one of the plurality of signal transmission lines changes when transitioning from a leading elementary period to a trailing elementary period of any two consecutive elementary periods; wherein the encoder encodes the input signal from a value from which the transmission signal can be obtained to a value excluding a predetermined specific value; and wherein if the value of the transmission signal to be outputted to the signal transmission lines in the leading elementary period of any two consecutive elementary periods is the same as the value of the transmission signal to be outputted to the signal transmission lines in the trailing elementary period, the encoder encodes the input signal to the specific value such that in that trailing elementary period the transmission signal of the specific value is outputted to the signal transmission lines.
