A STUDY OF DIGITAL FILTERS.
Abstract
The thesis discusses the subject of digital filters in two parts. First the analytical tools and synthesis techniques which are used for digital signal processors are explained and illustrated with examples. Emphasis is placed on (1) the generation and use of the digital transfer function, (2) design procedures in the frequency domain using methods of continuous-filter design as intermediate steps, and (3) real-time digital-filter implementation schemes. In the second part of the thesis a machine-language computer program is presented for the real-time simulation of digital filters on a hybrid computer. The program is described in detail and experimental results for several filter designs and realization schemes are reported. It is believed that such a computer program, with its inherent ability to accurately simulate a special-purpose computer and to provide external control of word length and clock frequency, could be used to experimentally determine specifications for the LSI implementation of digital filters.
