Transforms
In the section Transforms libraries Signal Operations The fast Fourier transform (FFT) is implemented to analyze the frequency components of the input signal, which allows converting the signal from the time domain to the frequency domain.
- DCT
-
Discrete cosine transform (DCT) of the input signal.
- FFT
-
Fast Fourier transform (FFT) of the input signal.
- IDCT
-
Inverse discrete cosine transform (IDCT) of the input signal.
- IFFT
-
Reverse fast Fourier transform (OBFT) of the input signal.
- Magnitude FFT
-
Nonparametric estimation of the spectrum by the periodogram method.
