Abstract
A signal transmission device includes a communication unit that is connected to an electronic device by a signal wiring and performs communication with the electronic device via the signal wiring, a signal processing unit that performs signal processing related to the communication, a power supply unit that supplies direct current to the electronic device via the signal wiring, and a filter circuit connected between the signal wiring and the power supply unit. The filter circuit includes a plurality of filters having frequency characteristics different from each other, and the signal processing unit acquires communication quality information indicating quality of the communication in at least two or more frequency bands, and determines a state of the filter circuit based on the communication quality information.
