... understand the basic characteristics of digital filters and familiar with techniques used for implementing digital filters. Many DSP books devote substantialefforts to the theory of designing digital ... characteristics of digital filters are often specified in the frequency domain. For frequency-selective filters, the magnitude response specifications of a digital filter areoften given in the form of tolerance ... realizable. Instead wemust compromise and accept a more gradual cutoff between passband and stopband, aswell as specify a transition band between the passband and stopband. The design isbased on magnitude...
