Document Type and Number:
Japanese Patent JP5569465
Kind Code:
B2
Abstract:
The fault diagnosis device is for diagnosing presence of a fault in an amplitude modulation device which modulates an amplitude of a carrier wave signal to generate a modulated wave signal, comprising. The fault diagnosis device includes a sampling means to perform sampling of at least one of the carrier wave signal and the modulated wave signal at a period different from a period of the carrier wave signal, and a diagnosis means to perform diagnosis of presence of a fault in the amplitude modulation device based on sampled values outputted from the sampling means.
