Hello,
I am using DSP TMS320VC5502. I want to find linear convolution of two
arrays. The first array XArray contain 5000 elements and the second array HArray
contain 200 elements. I need a resultent array YArray which is the linear
convolution of the two input arrays. The YArray should contain 5199 elements. I
tried the library function
convol2 (XArray, HArray, YArray, 5200,200)
But here we are doing circular convolutio and the resultant array
contains only 5200-200= 5000 points. How can we find linear convolution by
making use of this circular convolution? Is there any other function or
algorithm to find Linear convolution.........?Pls help...
Regards
Aravind

Hi Aravind,
conversion of circular convolution to linear convolution is clearly given in
the book Digital signal processing by Ramesh babu. I hope it helps you.

Thanks yar............
i have done the linear convolution through circular convolution by padding Zeros in the Xarray.But the zero should be inserted at the begining of the array.(In theory from "Ramsh babu" the zero should be insetred at the end..)
