Abstract:
The invention, upon receiving an input signal, sums the absolute values of the difference of each pair of values adjacent to each other within a series of detected signal values to suppress the interference of low-frequency noise. Furthermore, the invention sums the absolute values of the moving averages of the differences of each pair of values adjacent to each other within a series of detected signal values to suppress both the interference of low-frequency noise and the interference of high-frequency noise. No synchronization with the input signal is necessary. The detection can be started at any phase of the input signal.
