Digital Signal Processor: A Tutorial Introduction to Digital Filtering
Ernest James Angelo · Bell System Technical Journal · 1981
Very-large-scale integration (VLSI) of digital electronic circuits has changed the hardware aspects of digital filters in a major way so that the use of such filters as components in commercial systems has become both economically feasible and technically desirable. Thus, large numbers of system engineers and circuit designers are now finding a need to learn about the properties of such filters, how they are used, and how they are designed. This paper is a first step toward meeting that need.
