Abstract
PURPOSE: To reject noise signal with a simple processing, by handling the input wave as the true signal, when the peak is positioned to the set time interval after a given time from the waveform starting point of input wave incoming.
CONSTITUTION: Input wave is inputted via the buffer amplifier 1 from the input terminal T, the peak is detected at the peak detector 2, and the peak detection signal is output from the output terminal 2'. The input wave is also fed to the leading time timer circuit 3 to detect the start point of waveform, and the leading time timer signal is output from the output terminal 3'. The leading time timer signal is fed to the peak strobe forming unit 4 to output the peak strobe signal from the output terminal 4'. Whether the peak detection signal of input wave is present or not within the time width of the peak strobe signal is detected.
