Abstract
Techniques for regulating a radio frequency (RF) output power of an antenna of a computing device are described. In an example a physical signal filter unit (PSFU) to filter a detection signal from a proximity sensor for regulating an RF output power of a device is described. The PSFU includes a first filter circuit to filter the detection signal and generate a first filter output signal and a logical inverter gate to generate an inverted detection signal based on the detection signal. The PSFU also includes a second filter circuit to generate a second filter output signal based on the inverted detection signal. The PSFU also includes a logical AND gate to perform a logical AND operation on the first filter output signal and the second filter output signal to generate a control signal for regulating the RF output power of an antenna of the computing device.
