Algorithms
| Algorithm | Description |
|---|---|
| Fast Fourier Transform | Efficient computation of the Discrete Fourier Transform using the Cooley-Tukey radix-2 algorithm |
| Power Spectral Density | Estimation of signal power distribution across frequencies using Welch's method |
| Discrete Cosine Transform | Real-valued frequency decomposition via cosine basis functions, computed through FFT |
Sub-domains
| Sub-domain | Description |
|---|---|
| Windowing | Window functions (Rectangular, Hamming, Hanning, Blackman) for FFT preprocessing |
