At the end is the code function for overlap save function for block convolution. Could you help me to do the add convolution please. The instructions are the following
function [y] = ovrlpsav(x,h,N) % Overlap-Save method of block convolution % ---------------------------------------- % [y] = ovrlpsav(x,h,N) % y = output sequence % x = input sequence % h = impulse response % N = block length % Lenx = length(x); M = length(h); M1 = M-1; L = N-M1; h = [h zeros(1,N-M)]; % x = [zeros(1,M1), x, zeros(1,N-1)]; % preappend (M-1) zeros K = floor((Lenx+M1-1)/(L)); % # of blocks Y = zeros(K+1,N); % convolution with succesive blocks for k=0:K xk = x(k*L+1:k*L+N); Y(k+1,:) = circonvt(xk,h,N); end Y = Y(:,M:N)'; % discard the first (M-1) samples y = (Y(:))'; % assemble output1. 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 1.
