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
| Name | Type | Description |
|---|---|---|
| FrequencyStep | Double | Normalized frequency step (FS = 1) for the Chirp Z-transform. |
| StartFrequency | Double | Starting normalized frequency (FS = 1) for the Chirp Z-transform. |
| StartRadius | Double | Defines the starting radius in the Z-plane. |
| StopFrequency | Double | Ending normalized frequency (FS = 1) for the Chirp Z-transform. |
| StopRadius | Double | Defines the ending radius in the Z-plane. |
