Abstract
The invention detects the difference between the maximum signal and the minimum signal at each of a plurality of cycles separately when a sine wave is received. All differences are summed for generating a single detected signal for suppressing the interference of low-frequency noise. No synchronization with the sine wave is necessary and the detection can start at any phase of the sine wave.
