Overview
This example works as Comb filters,which are used in a variety of audio and signal processing algorithms.
Description
Comb filters are used in a variety of audio and signal processing algorithms, include implementing echo and flanging effects. The simplest structure of a comb filter is the feed-forward comb filter that has the form y = x + ax[n-K], where K is an integer delay and a is a scaling constant.
Requirements
Software
- LabVIEW 2012 or compatible
Steps to Implement or Execute Code
- Specify the frequency you want to remove and your sampling rate and your block size.
- The VI will determine the delay K.
- Adjust the block size and sampling rate to see how this affects your frequency resolution and hence the quality of your filter.
