Abstract
A modulated light receiver includes a photo-sensitive element, an electromagnetic interference (EMI) detection circuit, and a decision-making controller. The photo-sensitive element is configured to generate an electrical signal in response to modulated light. The electromagnetic interference (EMI) detection circuit is configured to generate an electrical signal in response to EMI. The decision-making controller is electrically coupled to the photo-sensitive element and the EMI detection circuit, wherein the decision-making controller generates an output based on the inputs received from the photo-sensitive element and the EMI detection circuit.
