Electronic control device

Abstract

An electronic control device includes: a circuit board configured to be provided in a frame and to have a communication circuit capable of receiving or transmitting differential signals via a pair of signal pins; a connector configured to be electrically connected to the circuit board and to input signals transmitted from an electronic device outside the frame by single-end transmission to the communication circuit; and a noise cancellation signal output circuit configured to output noise cancellation signals corresponding to noise superimposed on the signals in the connector, wherein one signal pin of the pair of signal pins of the communication circuit is connected to the connector, and the other signal pin is connected to the noise cancellation signal output circuit.
