List 3-5 frequency domain features that can be used for identification and classification purposes

Solution

The following feature can be extracted easily from the FFT of the signals and is commonly used in industry for classification of signal

For example identifying noise signal message signal spectrum identification, and also in the process of channel characterisation in some DSL transmission application.

1. Mean

2. Correlation

3. Spectral roll-off

4. Spectral centroid

5. Spectral flux
