Chapter 8Filter Models
Virtually all communication systems include filters. Some of these filters are included by design and others are included unintentionally by the unavoidable bandlimiting nature of certain system components. The ability to adequately model these filters is critical to the success of many simulation projects.
8.1 Modeling Approaches
Modeling of filters actually comprises two distinct tasks: (1) design of the desired filter response to meet specified requirements or to accurately represent portions of an actual system, and (2) mechanization of the filter so that a sequence of input samples is processed to produce a sequence of output samples. The design task has been an essential part of communications engineering for decades, ...
