IIRIIR Filter Functions
- X(eiφ)is the Fourier transform ofx(n)
- H(eiφ)is the Fourier transform ofh(n)
- Y1(eiφ)is the Fourier transform of the forward filter pass
- The filtered signal has zero-phase distortion (as the filtering was done with|H(eiφ)|, which is purely real-valued)2
- The filter transfer function has the squared magnitude of the original filter transfer function
- The filter order is double the order of the initialized IIR filter
