Abstract: To adequately perform sampling, a receiving device that solves problems that involve an increase in circuit area and an increase in cost, is provided. A/D converter 2 samples a coherent signal that is an analog signal in synchronization with a sampling clock signal so as to convert the analog signal into a digital signal. DSP 3 demodulates the digital signal converted by A/D converter 2 and computes a phase of the sampling clock signal in which an error rate of the digital signal is the minimum based on the demodulated digital signal. Sampling clock extraction circuit 4 extracts a clock signal having a symbol rate of the coherent signal therefrom. Phase adjustment circuit 5 adjusts the phase of the clock signal extracted by sampling clock extraction circuit 4 to the phase computed by DSP 3 and generates a clock signal having the adjusted phase as the sampling clock signal.

Abstract: In power line communications using carrier waves of high frequencies in the MHz range such as 2 to 30 MHz, when a coaxial cable for performing transmission of signals and a power line are signal-coupled using a capacitive signal coupling unit, even if an impedance matching circuit is installed in the capacitive signal coupling unit, we have found that leakage current of levels that cannot be neglected from leakage noise considerations flows through the outer sheath of the coaxial cable that transmits the signals, and, accordingly, leaking electromagnetic waves induced by the leakage current flowing through the coaxial cable due to impedance mismatch between the power line and the capacitive signal coupling unit are reduced by an impedance member showing high impedances at high frequencies in the MHz range.
