1. Make a program to calculate the linear convolution of two sequences, calculate y (I) = x (m) * H (n), draw the graph of X (m) and H (n), and the graph of the linear convolution result y (I), and use the conv function of MATLAB to verify the result.
2. The FFT and IFFT programs of MATLAB are used to realize the fast calculation of linear convolution and draw the calculation results.
