I am trying to convolute two time doamin signals. singal 1 is imported to matalb as a FD signal while i am creating signal2 in matlab so i do create it in TD.
(1) convert signal1 to TD and perform direct convolution with signal2
(2)Keep signal1 in FD ,convert signal 2 to FD, and perform multipication. then convert the results back to TD
I need the final results to be in TD.
However, Both reaults dont agree. Can someone Please help me to figure out the reason?
