Abstract
To realize a transmission function of power line communication by a further simplified and cost-effective circuit configuration, in a PLC modem installed in an electric appliance such as a household electrical appliance. A semiconductor switching element that is present on an electric circuit connected to a power line is driven by a modulator unit. The modulator unit controls ON/OFF operations of the semiconductor switching element, to thereby cause a communication signal of a modulated rectangular wave to be output to the power line for a prescribed period.
