Sensitivity of the band-edge selectivity of various classical filters

Sensitivity of the band-edge selectivity of various classical filters

Many filters have a band-edge selectivity (BES) that is a function of parameters other than filter order. When this is the case, the band-edge selectivity of these filters can be maximized without increasing their order. However, we must temper our intent by the sensitivity of the BES to the varying...

Zusammenfassung:Many filters have a band-edge selectivity (BES) that is a function of parameters other than filter order. When this is the case, the band-edge selectivity of these filters can be maximized without increasing their order. However, we must temper our intent by the sensitivity of the BES to the varying parameters. We study here the sensitivity of the band-edge selectivity of various classical filters, these being described by polynomials approximating the ideal brick-wall filter magnitude response.
