Introduction to Digital Filters
Trevor J. Terrell · 1980
In this chapter, digital filter are discussed. Digital signal processing (DSP) is an established method of filtering electrical waveforms and digital images, and it is an important topic in a number of diverse fields of science and technology. The realisation of the many practical applications has been made possible by the increased availability and falling costs of sophisticated very-large-scale integrated (VLSI) circuits. In particular, the ubiquitous microprocessor and associated peripheral chips provide the means of implementing relatively simple and cost-effective digital filters.
