Title:
SIGNAL TRANSMISSION DEVICE, SIGNAL TRANSMISSION SYSTEM, INFORMATION PROVISION METHOD
Document Type and Number:
WIPO Patent Application WO/2022/097395
Kind Code:
A1
Abstract:
This signal transmission device comprises: a communication unit that performs communication by differential transmission with an electronic device via differential wiring; and a signal processing unit that performs signal processing pertaining to the communication. The communication unit can receive, via the differential wiring, communication signals transmitted from the electronic device at multiple signal transmission speeds including at least a first signal transmission speed and a second signal transmission speed that is slower than the first signal transmission speed. The communication unit measures the amplitude of the communication signals received from the electronic device at the second signal transmission speed. The signal processing unit detects a short-circuit fault in a filter circuit on the basis of the amplitude measured by the communication unit.
