“…The higher the SNR the better is the signal quality [242,245,246]. The most popular signal processing methods applied for the purpose of analysis of biomedical data are various Transforms, such as [3,26,40,53,58,227,240,[246][247][248][249][250][251][252][253][254][255][256][257] Fast Fourier Transform (FFT)-frequently applied in analysis of any deterministic bio-signal's spectral content, which is also a faster version of the Fourier (FT) and the Discrete Fourier (DFT) Transform.…”
