Title: SIGNAL PROCESSING SYSTEM AND SIGNAL PROCESSING METHOD
Abstract:
A signal processing system and a signal processing method. The signal processing system comprises: an output device (301) comprising a first positive output end and a first negative output end; a first comparator (302) comprising a second positive input end and a second negative input end, the second positive input end being connected to the first positive output end, the second negative input end being connected to the first negative output end, and used for shaping on a first positive signal (V1p) and a first negative signal (V1n) to generate a second signal (V2p); a second comparator (303) comprising a third positive input end and a third negative input end, the third positive input end being connected to the first negative output end, the third negative input end being connected to the first positive output end, and the second comparator (303) being used for performing shaping on the first positive signal (V1p) and the first negative signal (V1n) to generate a third signal (V2n); a multiplexer (304) used for selecting the second signal (V2p) or the third signal (V2n) to generate a fourth signal (V4), the fourth signal (V4) having an accurate rising edge; and an edge trigger (305) used for performing edge transition according to the rising edge of the fourth signal (V4) to generate a fifth signal (V5).
