A signal processing method according to the present disclosure is for use in a signal processing system including a first magnetic detection unit, a second magnetic detection unit, and a processing unit. The signal processing method includes an angle calculating step and a failure diagnosis step. The angle calculating step includes transforming, by using an inverse trigonometric function, a sine signal, a cosine signal, and a tangent signal into a first angle signal, a second angle signal, and a third angle signal, respectively. The failure diagnosis step includes making a failure diagnosis of the first magnetic detection unit and the second magnetic detection unit by comparing with each other two or more pieces of angle information selected from first angle information, second angle information, and third angle information.

A switch is inserted and connected between a first portion and a second portion of an HPD line. The switch connects the first portion to the second portion when an HPD signal is outputted to the second portion. The switch cuts off the connection between the first portion and the second portion when the HPD signal is not outputted to the second portion. An AND gate generates a connection state detection signal that represents the connection state of an HDMI optical active cable, and outputs the connection state detection signal to a switch.
