- DESA-1 and NLE OPERATOR
- License: Freeware

In this algo, DESA-1 is implemented and the use of NLE operator is visible. DESA-1 is taken and implemented as described by keiser .Non Linear Operators were introduced by Teager and further introduced by Maragos and Keiser.The algo presented here is simple to use ,low in complexity and can be applied to a variety of signals. At the end ,I have tried to check the results with those obtained in the traditional calculatios.

- ESTIMATION PROCESS USING NON LINEAR ENERGY OPERATOR

Estimation of various parametres of any signal is of prime importance in signal analysys. Here we are using Non Linear Energy operator introduced by Keiser and first provided by Teager.The algo is approaching DESA-1 . To estimate instaneous frequency and amplitude ,this process is quite useful and it can well be applied to other time varring signals as well.

With improvements in signal processing some new models with enhanced features are made available.TVAR is on similar pattern.This model is better than conventional am-fm model in some respect as it facilates the implementation of same algo on various signals bearing different parameters. Use of Non LInear Energy (NLE)operator is an important aspect. HOpe this will be of help to others using matlab.The algo is present within code.
