CalcChebFilterCoeffs 

The procedure CalcChebFilterCoeffs calculates the coefficients of a Chebychev filter. The calculated coefficients CoeffA0 and Coeffs can be directly used by the routine ChebychevFilter to apply a Chebychev filter to a series of signal values. The parameter NPoles defines the number of poles of the filter and has to be an even number between 2 and 20. The parameter HiLoP determines whether a highpass (HiLoP = TRUE) or a lowpass (HiLoP = FALSE) filter is to be created. The parameter CutOffFQ controls the cutoff frequency, which is specified as a fraction of the sampling rate. Thus the CutOffFQ parameter may assume values between 0 and 0.500. The parameter Ripple determines the percent ripple in the passband (allowed values: 0 to 29).
