Analyze the physics significance of the convoluting in time domain and the weighting in frequency domain in detail by using the digital low pass filter as the exemplification.And by using the MATLAB sound processing function as the data connection,the multimedia players as the interactive contact surface,the MATLAB FDATool as the filter design tool,designed a group of experiments for audio low pass filter with the purpose of strengthening the understanding of the digital signal processing by comparing the change of the audio effect before and after the filter.
