Square wave reference digital lock-in detection using non-orthogonal demodulation
Digital lock-in detection technique is commonly used to measure the amplitude and phase of a selected frequency signal. The technique which uses a square wave as the reference signal has an advantage of easier implementation and higher computational efficiency compared to that uses a sine wave. Howe...
