Review of digital filtering
J.D. Heightley · 1970
Digital filtering embodies a wide range of signal processing and sianalyzing applications but this paper is concerned with the more conventional filtering requirements of frequency selection and rejection. Some of the principles involved in digital filtering are discussed from an intuitive point of view rather than in terms of the wellestablished mathemtical treatments. The form of a general second order filter eection is established using this intuitive approach and the extension to higher order filters is discussed.
