Transforms
In the section Transforms libraries Signal Processing 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
-
Performs non-parametric spectrum estimation using the periodogram method.
