Homework: (Due: June 30)

(a) Develop a MATLAB function to implement the overlap-add method using the circular convolution operation.

The format should be

--------------------------

function [y] = ovrlpadd(x,h,N)

% Overlap-Add method of block convolution

% [y] = ovrlpadd(x,h,N)

%

% y = output sequence

% x = input sequence

% h = impulse response

% N = block length >= 2*length(h)-1

-----------------------------

(b) Incorporate the radix-2 FFT implementation in the above function to obtain a high-speed overlap-add convolution routine. Remember to choose N = 2^v

Verify your functions on the following two sequences

x(n) = cos(pn/500)R₄₀₀₀(n), h(n) = {1, -1, 1, -1}

where R_M(n) is a rectangular window function, that is

R_M(n) = 1 for 0 £ n £ M - 1

R_M(n) = 0 for n £ 0 and n > M - 1
