A Digital Extraction Method of Gaussian Pulse Signal Timing Point

Abstract

In this paper, a Gaussian interpolation timing point extraction algorithm based on FPGA is implemented. According to the problem that the timing point error is less than 6ns cannot be satisfied when the effective digit is less than 7 bits, an improved algorithm for accurately extracting Gaussian pulse timing point based on FPGA is designed. Analyzed the source of timing error, the comparison of maximum error between the direct extraction algorithm, Gaussian interpolation algorithm and the improved Gaussian interpolation algorithm is presented when the sampling number is 7 and the peak is full scale. It is concluded that the improved Gaussian interpolation timing algorithm can effectively improve the timing accuracy.
