摘要： A transmitting circuit 10 converts transmission data to a multilevel analog signal suitable for transmission. The multilevel analog signal is output to a cable 21 via an amplifier and a hybrid circuit 12. In the transmitting circuit 10, a waveform which compensates waveform deterioration at the cable 21 is generated. A reception signal from the cable 21 is input to a mixer 14 via the hybrid circuit 12 and an amplifier 13. The mixer 14 mixes the reception signal and a cancel signal output from a cancel signal generation circuit 17 so as to remove undesired signals. In a receiving circuit 15, the signal output from the mixer 14 is sampled by use of a plurality of sample-hold circuits, and subjected to analog sum-of-product computation which is performed by a matrix circuit for distortion compensation. Subsequently, the sampled signals are converted to digital signals. The digital signals are collectively subjected to processing such as parallel-serial conversion, whereby reception data and an evaluation signal are obtained. An adjustment control circuit 18 includes a CPU, and adjusts the respective circuits on the basis of the evaluation signal such that data can be correctly transmitted and received.

摘要： Transmission equipment that can be used up to a high frequency and simplifies a circuit design includes a THP preceding means on a transmitting side, and an equalizer means, wherein analog processing is carried out on a receiving side. Compensation of the frequency characteristic of a transmission channel is divided into the THP preceding means on the transmitting side and the equalizer means, so that due to compensation by the equalizer circuit, the absolute value of a THP coefficient becomes small, and a DAC with lower resolution, wherein stability of a loop of the THP increases, can be used. Detailed adjustment for adapting to the characteristic of a transmission channel is carried out by the THP, so that the equalizer circuit is only required to roughly compensate, and is not required to adjust. As a result, the equalizer circuit can be of a simple design.
