RECEPTION CIRCUIT, RECEPTION METHOD AND SIGNAL TRANSMISSION SYSTEM

摘要

A signal transmission system has ADC converting a signal which a reception circuit receives into a digital signal of multiple bits and operates ADC with an optimum condition in accordance with an actual signal transmission state. The reception circuit is provided with an AD converter, an equivalent circuit equalizing the digital signal which the AD converter outputs and generating reproduction state information showing a reproduction state of the received signal and an adjusting circuit adjusting at least an input quantization range or resolution of the AD converter based on reproduction state information from the equivalent circuit.
