Abstract:
1. An adaptive equalization circuit equipped by an adaptive equalization control unit for controlling an equalizer circuit which equalizes an equalization object signal, comprising: an identity detection unit for detecting an identity between a preset data pattern and a data pattern output from the equalizer circuit; a monitor unit for sequentially monitoring an output of the equalizer circuit and inputs to a plurality of gain amplifiers included by the equalizer circuit, every time the identity detection unit detects the identity between the preset data pattern and the data pattern; and an operation control unit for making the adaptive equalization control unit operate an adaptive equalization control by providing the adaptive equalization control unit with the result of monitoring, wherein the result of monitoring are the output of the equalizer circuit and the inputs to a plurality of gain amplifiers, wherein the monitor unit circuit includes a plurality of first analog/digital converters each of which receives the corresponding input to a plurality of gain amplifiers.
