【Abstract】 A basic experiment of "digital filter design" is developed to meet the needs of applicability in digital signal processing course.By taking comb filter as an example, the digital filter is simulated with software and implemented with virtual instrument platform. The measured data from virtual instrument platform and simulation results are discussed to analyze the performance of comb filter with different structures and parameters. The experimental contents involve sampling of analog signals, filter design and implementation, signal recovery, covering the important contents in digital signal processing course. The experiment deepens students’ knowledge and understanding of digital filter design and signal processing, improves students’ ability of exercise and combination of theory with practice.更多还原
