This is an interactive filter design package, for designing digital. H .

Chapter 33: The z-Transform

The amount of attenuation for each frequency depends on the filter design. If the succession of narrow band filters includes the real axis, we have a low pass filter. Digital Filters and Z Transforms So, the Z transform of the inverse filter is just the reciprocal of the Z transform of the filter. The area of filter design involves many types, such as: low pass, high pass. Frequency Response - MATLAB On this page Digital Domain.
