Abstract:
Provided are a data transceiver and method for performing equalization and pre-emphasis adaptive to the transmission characteristic of a transmitting part. The transceiver measures the signal attenuation characteristic of a transmission line of a receiving part using an input data signal input via the transmission line of the receiving part, decodes the distorted waveform of the input data signal, distorts the waveform of an output data signal beforehand using the measured signal attenuation characteristic of the transmission line of the receiving part, and transmits the output data signal via a transmission line of a transmitting part. Thus, when the output data signal is transmitted via the transmission line of the transmitting part, the waveform of the signal remains optimized.
