TSpectrumCZT Class

public class TSpectrumCZT

Encapsulates parameters required by chirp-Z transform.

Chirp Z-transform, can evaluate the frequency spectrum by starting and ending at any frequency and calculating frequency bins with any frequency step. Chirp Z-transform is more efficient then FFT, if zero padding is required.

Properties

NameTypeDescription
FrequencyStepDoubleNormalized frequency step (FS = 1) for the Chirp Z-transform.
StartFrequencyDoubleStarting normalized frequency (FS = 1) for the Chirp Z-transform.
StartRadiusDoubleDefines the starting radius in the Z-plane.
StopFrequencyDoubleEnding normalized frequency (FS = 1) for the Chirp Z-transform.
StopRadiusDoubleDefines the ending radius in the Z-plane.
