ABSTRACT:
A method and device for recognizing a waveform of an analog signal into a binary digital signal is developed. The method includes a) inputting the analog signal, b) determining voltage values of every peak and every valley of the analog signal respectively, c) determining a plurality of threshold voltages for the analog signal such that each the threshold voltage corresponds to mutually adjacent peak and valley and two adjacent respective the threshold voltages have a corresponding common one of the respective peak and the respective valley, and d) comparing each point of the waveform of the analog signal with the corresponding threshold voltage respectively for obtaining the digital signal. A real time device with a simple circuit is also available.
