Abstract
A communication device according to an embodiment includes an oscillator, a first signal generation circuit, a first insulation element, a first receiving circuit, and a first output circuit. The oscillator is configured to output a first carrier signal when at least one of a plurality of input signals that are externally input is at a first logic level. The first carrier signal and a first input signal among the input signals are input to the first signal generation circuit. The first signal generation circuit is configured to generate a first signal when the first input signal changes from a second logic level to the first logic level, output a first modulated signal based on the first signal, and thereafter output a second modulated signal based on the first carrier signal.
