More Information
Summary:A wireless receiver and transmission systems include a receiver antenna, a sensor, a demodulation circuit, and a controller. The sensor is configured to detect electrical information superimposed on an AC wireless signal. The demodulation circuit is configured to receive the electrical information from the at least one sensor, apply automatic bias control and gain control to generate modified electrical information, detect a change in the modified electrical information and determine if the change in the modified electrical information meets or exceeds one of a rise threshold or a fall threshold. If the change exceeds one of the rise threshold or the fall threshold, an alert is generated. Alerts are decoded into the electrical information.
