Convolution without using conv

5 views (last 30 days)
I want to find the convolution between x1 and h1 (and for all the other pairs). Both functions from the screenshots are defined for n=[-25:25], all i need is to find how to calculate their convolutions.

Get your program working first before you worry about optimization.
  • write a u function.
  • write a function for each of your formulas. Each one can have a for loop over its inputs, and if/elseif to calculate the outputs.
  • Now calculate each over -25:25
  • then calculate the convolution

I am at calculating the convolution part but i dont know how. Don't i need convolution to find the output?

It shows you the summation you need to use. The only trick is in knowing to clamp the mininum and maximum limits to avoid going out of bounds if you are near an edge.
