First, the purpose of the experiment 1. master the method of producing typical sequence. 2. master the realization method of DFT and use DFT to analyze the signal in frequency domain. 3. familiar with the change of the frequency spectrum before and after the continuous signal sampling, deepen the understanding of the time domain sampling theorem. 4. the time domain and frequency domain characteristics of the convolution and DFT analysis signals and systems are used to verify the time domain convolution theorem. Two. Experimental environment 1. Windows2000 operating system 2. MATLAB6.0
