An electronic apparatus which is capable of detecting faults that cannot be detected with a fixed signal pattern and which also permits fault detection to be performed even during the operation thereof. Signal processor circuits perform identical signal processing, and a signal router causes the signal being input to an operating signal processor circuit which is performing the signal processing among the signal processor circuits, to be input to an idle signal processor circuit which is not performing the signal processing. A fault detector compares an operating output signal output from the operating signal processor circuit with an idle output signal output from the idle signal processor circuit to detect a fault.
