• Manufacturer Part Number: AN2384
• Description: Generic Tone Detection Using Teager-Kaiser Energy Operators on the StarCore SC140 Core
• Manufacturer: Freescale Semiconductor / Motorola

Use of the Teager-Kaiser energy operator in tone detection applications yields a number of significant advantages:
faster response, versatility, improved time resolution, independence between time and frequency resolutions, ease
of maintenance and fine tuning. Additionally, the decision logic has very few control parameters, which can easily
be adjusted for different tone formats. The TK-based algorithm is inherently simple to reuse and support, and it can
deliver generic tone detection functionality and performance comparable to or better than that of classical methods.
