1. Write a Matlab function to convolve two sequences objects: function y = conv(x, h) % CONV Convolve two finite-length Matlab sequence objects, x and h % returning sequence object, y. When you convolve x[n] and h[n] , you may not use MATLAB's numerical conv routine. 2. write a second convolution function, conv_rt, in Matlab that basically implements a real-time convolu- tion strategy: function y = conv_rt(x, h) % Convolve two finite-length arrays, x and h % returning array, y...
