Konstruktordetails

RectBandpass

public RectBandpass(double lowerCutoffFrequency,
 double upperCutoffFrequency)

Parameter:

lowerCutoffFrequency - lower cutoff frequency - 6 db (Grenzfrequenz mit H(f) = 0.5)

upperCutoffFrequency - upper cutoff frequency - 6 db (Grenzfrequenz mit H(f) = 0.5)

Methodendetails

getLowerCutoffFrequency

public double getLowerCutoffFrequency()

getCoeff_CarrierMeth

public static double[] getCoeff_CarrierMeth(int coefficients,
 double fl,
 double fh,
 double ta)

Generates the coefficients of a bandpass filter. Base band lowpass - carrier method.

getCoefficients

public static double[] getCoefficients(int coefficients,
 double fl,
 double fh,
 double ta)

Generates the coefficients of a bandpass filter. Upper lowpass minus lower lowpass method.

notifyBeforeParameterChange

public void notifyBeforeParameterChange(Parameters changedParameters)

Parameters have changed (a copy of the systems parameters has been changed by the user). System is allowed to check parameters, change parameters and feed accepted parameter values back to parameters. PropertyWindow displays the updated parameter values.
