Detailed Description
A simple low pass.
This class defines a simple IIR low pass filter as described in Numerical Recipes p. 562. The filter coefficients are calculated by a bilinear transformation method. The corner frequency in the constructor has to be given in terms of the Nyquist frequency, i.e. in the range
