Constructor Detail

ChebyshevII

public ChebyshevII(int order,
                   double epsilon,
                   PassbandType type,
                   double f1,
                   double f2,
                   double delta)

Instantiates a new Chebyshev type II filter.

Parameters:

order - int specifying the order (number of poles) of the filter.

epsilon - double design parameter specifying the passband ripple and stopband attenuation.

type - PassbandType specifying whether the filter is a lowpass, bandpass or highpass filter.

f1 - double specifying the low cutoff frequency (must always be present, but used only for bandpass and highpass filters).

f2 - double specifying the high cutoff frequency (must always be present, but used only for bandpass and lowpass filters).

delta - double specifying the sampling interval of the data to which this filter will be applied.
