Summary

EEG has noise (muscular activities, blinking of eyes, power line electrical noise), methods have been introduced to eliminate these unwanted signals

1. Fast Fourier Transform
2. Wavelet Transform

• Continuous Wavelet Transform
• Discrete Wavelet Transform

3. Eigenvectors
4. Time-Frequency Distributions
5. Autoregressive

Frequency domain methods may not provide high-quality performance for some EEG signals. In contrast, time-frequency methods, for instance, may not provide detailed information on EEG analysis as much as frequency domain methods.
