ABSTRACT
The purpose of this thesis is to formulate a technically sound approach to designing Infinite Impulse
Response (IIR) digital filters using high-level modeling tools. High-level modeling tools provide the ability
to build and simulate ideal models. Once proper validation plete on these ideal models, the user
can then migrate to lower levels of abstraction until an actual real world model is designed. High-level
modeling tools are the epitome of the top-down design concept in which design first takes place with the
basic functional knowledge of a system. With each level of abstraction, validation is performed. High-level
modeling tools are used throughout industry and their application is continually growing especially in the
DSP area where many modes munications are expanding. High-level modeling tools and validation
significantly address plex expansion by utilizing an ideal representation of work.
