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
3. Write a function to deconvolve an output sequence:
function x = deconv(y, h)
% DECONV Convolve finite-length Matlab sequence object, y, % given
impulse response sequence object, h
% returning sequence object, x.

Question 1: MATLAB contains a built-in function called conv which performs the convolution of two vectors: >> help conv conv Convolution and polynomial multiplication. C - conv(A, B) convolves vectors A and B. The resulting vector is length MAX ([LENGTH (A)+LENGTH (B)-1, LENGTH(A),LENGTH (B) 1) If A and B are vectors of polynomial coefficients, convolving them is equivalent to multiplying the two polynomials. Compute the system response...
