Abstract
Multi-rate digital signal acquisition and processing technology is a general term that refers to changing the sampling rate of the signal through extraction or interpolation. In the acquisition and processing of a variety of digital signals such as our country’s petroleum resources survey, in order to meet the differences of various modules the sampling rate is required, and the multi-speed digital signal acquisition and processing technology has also received great attention. This article focuses on the research of FPGA-based multi-rate digital signal processing software. After analyzing the current situation of multi-rate digital signal processing, we will understand the application of FPGA in multi-rate digital signal processing, and then learn about FPGA-based multi-rate digital signal processing. The software is designed, and the designed software is tested, and the test is performed for the stability of the software. The test result is that the temperature of the software starts to stabilize after 1-2 hours of work, and then the test is performed for the software signal acquisition. The test result is the signal-to-noise ratio of the designed analog-to-digital conversion circuit can reach 85dB, and the effective number of bits can reach 13bit.
