%Homework 2 Problem 3.7
%ECE 301 Summer 2009
%This Program computes the convolution of two inputs x(t) and h(t)with the
%final output being y(t).
%The user will enter a sequence of numbers for x(t) and numbers for
%h(t) in the form of a vector.
%The program below will compute the convolution, y(t), based on the users
%input.
%Part 1: Asks for input values from user.
x = input('Enter a sequence of numbers, x, EX: [1,2,3]: ');
h = input('Enter a second sequence of numbers, h, EX: [1,2,3]: ');
%Part 2: Calculates length of vector specified by the user.
Lgthx = length(x); %%The Length of vector x specified by user.
Lgthh = length(h); %%The Length of vector h specified by user.
%Part 3: Pading the 2 vectors from above with their zeros (Makes answers more accurate).
X=[x,zeros(1,Lgthh)]; .
H=[h,zeros(1,Lgthx)];
%Loop Used for the Convolution Computation
for(i = 1:Lgthx + Lgthh - 1)
y(i) = 0;
for(j = 1:Lgthx)
if(i - j + 1 > 0)
y (i) = y(i) + X(j) * H(i-j+1);
end
end
end
y %Displays the final output, y.
