xFFT
Initialize
Initializes the object. You can add parameters to this method if needed.
Forward
Calculates the forward FFT (Fast Fourier Transformation)
Real() = the real part of the time signal, the imaginary part is supposed to be 0 managed internally
The length of Real must be a power of 2?
Returns the amplitude of the frequencies
Example code<code>
FFTMagnitude = FFT1.Forward(Real)
</code>
Double()
Real
Double
Inverse
Calculates the inverse FFT (Fast Fourier Transformation)
Real() = the real part of the frequency
Imag() = the imaginary part of the frequency
The length of Real and Imag must be a power of 2 + 1
Returns the real values of the time signal
Example code<code>
TimeRealINV = FFT1.Inverse(Real, Imag)
</code>

Real
gets the FFT Real array
Double()
Imag
gets the FFT Imaginary array
Double()
Magnitude
gets the FFT Magnitude array
Double()
Phase
gets the FFT Phase array in radian or degrees depending on ModeDegrees
Double()
ModeDegrees
gets or sets the Degree mode
ModeDegrees = True reutuens the FFT Phase in degrees instead of radians
Boolean
Window
gets or sets the FFT window
possible values "NONE", "Hann"
