Matlab Code for Convolutin%function [Output] = ConOwn( In,Impl )%%%%%% this function takes input as INput samples and Impulse response as%%%%%% function arguments and return the output samples in the array called%%%%%% output array <<<>>>If the lenght of the input samples by the users%%%%%% are not equal then zero padding is done to make them equal using%%%%%% inbuild matlab command length and%%%%%% zero(1,m)<><><><><><><><><><><>< Convoultion function is performed%%%%%% by using backward difference equation Y_new=Ynew+Sum[Saved Data]% Detailed explanation goes here m=length(In); n=length(Impl); In=[In,zeros(1,n)];Impl=[Impl,zeros(1,m)]; for i=1:n+m-1 Output(i)=0; for j=1:m if(i-j+1>0) Output(i)=Output(i)+In(j)*Impl(i-j+1); end end end figure(); plot(Output,'--yd','LineWidth',5,... 'MarkerEdgeColor','m',... 'MarkerFaceColor','r',... 'MarkerSize',5); xlabel('time'); ylabel('amplitude'); title('ramp signal'); title('The Covnvolved Signal Plot')
