Convolution

Convolution between two finite sequences

Algorithm

Convolution of two signals is defined as y (n) =x (n)*h (n) =∑ x (k)*h (n-k), upper limit=∞, lower limit =0

1. Input the signal sequence x(n)

2. Input the signal sequence h(n)

3. Convolve the both sequence by making use of the MATLB function "conv(x,h)" where x and h are the sequences to be convolved

Program

x = input(' Enter the sequence x(n) : ');

h = input (' Enter the sequence h(n) : ');

y= conv(x,h); %Do the convolution operation

plot (y);

xlabel('time index n');

yalabel(' y(n) ');
