Equalizer, equalization method, and transmitter

摘要

An equalizer includes a waveform detection circuit, an equalization transmission circuit, and an equalization parameter setting circuit. The waveform detection circuit observes a first characteristic parameter of a first input signal. The equalization transmission circuit outputs an equalization transmission signal obtained by changing a second input signal based on a predetermined equalization parameter. The equalization parameter setting circuit sets the equalization parameter based on the first characteristic parameter. A transmission line which supplies the first input signal and a transmission line to which the equalization transmission signal is output have mutually similar transmission properties.
