Summary
Chebyshev's window.
Unit
SignalUtils
Declaration
Function Chebyshev(Src: TVec; AttdB: TSample; Index: integer = 0; Len: integer = -1): TVec;
Description
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.
