# LINEAR CONVOLUTION USING DFT AND IDFT PDF

Linear Convolution Using DFT. ➢ Recall that linear convolution is when the lengths of x1[n] and x2[n] are L and P, respectively the length of x3[n] is L+P What if we want to use the DFT to compute the linear convolution instead? We know x3[n] = IDFT(DFT(x1[n]) · DFT(x2[n])) will not work because this performs. circular convolution without using cconv(). 9 Downloads. LINEAR CONVOLUTION, 8 Downloads. imread_big — read in TIFF stacks larger than 4GB.
