Overview

The purpose of this VI is to eliminate, in software, the presence of an unwanted frequency spike, mainly at the 0-1 Hz range.

 

Description

This VI simulates a 1 Hz sine wave, with added noise to the signal. It takes the FFT of the simulated signal and filters out the frequency spike/response induced by the FFT. It accomplishes this by simply collecting the data into an array, and zeroing out the targeted frequency (1 Hz). See attached VI for full code.

 

Requirements

  • LabVIEW 2014 (or compatible)

 

Steps to Implement or Execute Code

  1. Run the VI.
