Second part of tone detection using TKEO

October 20, 2012

It’s been almost a year since I put up my last tutorial about tone detection using the Teager Kaiser Energy Operator.  I have finally written something up for part two here.  Life with a young family has been quite busy for me.  If there is enough interest in the TKEO stuff, I may write a part 3 showing a fixed point version (another year from now?).

Let me know if there are any problems with formatting in the code (something that always seems to be a problem). Copying the code is easy.  If you put your mouse pointer over any of the code listings, a number of symbols will be shown at the top right.  One of these will allow the code to be copied to the clipboard.

New Post on Tone Detection

November 8, 2011

I’ve added a new page introducing the use of the Teager Kaiser Energy Operator (TKEO) for determining the frequency of a tone (sinusoid). The page is here.  I’m planning a couple of more pages to show how to improve conditions in noise, how to reduce execution time, and how to make a fixed point version.
