TVec Chebyshev(TVec Src, Double AttdB, Int32 Index, Int32 Len)
Chebyshev's window.
| # | Name | Type | Description |
|---|---|---|---|
| 1 | Src | TVec | source TVec |
| 2 | AttdB | Double | scalar |
| 3 | Index | Int32 | start index |
| 4 | Len | Int32 | element count |
Returns: TVec
Remarks:
Applies Chebyshevs equiripple window to Src. The attenuation of the spectral leakage is defined with the AttdB parameter in [dB].
Window functions are applied to the signal prior to conversion to frequency domain with the FFT algorithm, to reduce the spectral leakage. Their side-effect is a lower frequency resolution.
