Abstract
A signal receiving device includes a first receiving circuit, a second receiving circuit, a third receiving circuit and a light-emitting device. The first receiving circuit is configured to receive a first electromagnetic wave and obtain a first signal from the first electromagnetic wave. The second receiving circuit is coupled to the first receiving circuit, and is configured to amplify an amplitude of the first signal output from the first receiving circuit to obtain a second signal. The third receiving circuit is configured to receive a third signal and output a fourth signal. The light-emitting device is coupled between the second receiving circuit and the third receiving circuit, and is configured to be in an off state when the second signal is the same as the fourth signal and in a light-emitting state when the second signal is different from the fourth signal.
