WebAdvantages of using digital filters The following list gives some of the main advantages of digital over analog filters. 1. A digital filter is programmable, i.e. its operation is determined by a program stored in the processor's memory. This means the digital filter can easily be changed without affecting the circuitry (hardware). Webroundoff noise of a digital filter can be easily computed once the digital filter is described in SVD form. In section 4.2, we review scaling operation and roundoff noise. Section 4.3 …
