 Overview: The output is a swept sine, only with more of the interval devoted to lower frequencies. 

Description: One of our analysts pointed out that the standard chirp library in LV gave a linear sweep, and he suggested an exponential sweep that would give more time in the lower frequencies.  Submitting it in the hopes that it may be useful.  The output is a swept sine, only with more of the interval devoted to lower frequencies.  This has proved useful in one of our applications that observes frequency-response.

 

Requirements: LabVIEW 2012 (or compatible). Hardware: none.

Steps to Implement or Execute Code: Uses the same arguments as the library Chirp. Play with different parameters.
