The present disclosure relates to an apparatus for recognizing a pulse signal, and more particularly, to an apparatus for recognizing a pulse signal, which maintains the pulse signal being input for ascan time until an end time point of the scan time, and stores the pulse signal in a pulse signal storage area as pulse input data. The apparatus for recognizing a pulse signal according to one embodiment of the present disclosure includes a signal maintaining unit configured to maintain and output the pulse signal, which is input for the scan time, as a pulse maintaining signal; a signal transmission unit configured to receive the pulse maintaining signal from the signal maintaining unit and transmit the input pulse maintaining signal based on a transmission control signal; and a control unit configured to output the transmission control signal to the signal transmission unit to receive the pulse maintaining signal, and store the received pulse maintaining signal in a pulse signal storage area as pulse input data.
