Can I read DSP Program: Noise Reduction and Filtering on EtoBox?

DSP Program: Noise Reduction and Filtering by Sandeep Banerjee is a document available to read on EtoBox.

What is DSP Program: Noise Reduction and Filtering about?

The program calculates the convolution of input signal x=[1 2 3 4 -1 -2 -3 0 1 2 0 -1 0 4 3] with impulse response h=[1 0 -1] using overlap-add method without built-in commands and compares the result with output of conv command. It divides the input into blocks of length L=4 with M-1=2 points of overlap. Circular convolution is performed on each block and results are added to get final output. The output is compared with that obtained using conv command to verify the overlap-add method.
