PURPOSE: A system for detecting a pulse signal and a method thereof are provided to reduce the occupancy area of a circuit by generating a pulse signal by using a digital video signal. CONSTITUTION: A plurality of ADCs(120) changes a plurality of analog signal into a plurality of digital video signal corresponding to each channel. A plurality of comparison units(130) compares digital signals with a predetermined threshold value. A pulse signal generator(140) generates a pulse detection signal according to a comparison result. |
