Apart from the obviousadvantages of virtually eliminating errors in the filter associated with passivecomponent fluctuations over time and temperature, op amp drift (active FILTERS ), etc., DIGITAL FILTERS are capable of performance specifications that would, at best, beextremely difficult, if not impossible, to achieve with an analog implementation.
consider when evaluating analog versus digital filters. Most modern signal processing systems use a combination of analog and digital techniques in order to accomplish the desired function and take advantage of the best of both the analog and the digital world. Figure 6.2 There are many applications where digital filters must operate in real ...
