The use of an Infinite Impulse Response (IIR) Digital Filter in the CT Data Collection System is studied. The material is presented with the assumption that one has a basic understanding of analog filters and z-transforms. Some knowledge of digital filters would also be helpful.

Chapter 1 begins with a description of the present CT Data Collection Architecture. The goals of the project are then discussed. Chapter 2 discusses the analog response to be compensated, and Chapter 3 discusses the current FIR Digital Filter that is used. In Chapter 4, the requirements (and design) of the IIR Filter is presented. Finally, Chapter 5 contains a summary of the results, the possible future development needed, and a brief discussion on hardware implementations.
