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

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.
