... Function /Selective Linear Phase Canonical FiltersAs mentioned above, the elliptic function response or selective linear phase re-sponse can be obtained in canonical form. For demonstration, consider ... producing asymmetricalfrequency response, which is desirable for some applications requiring only a high-er selectivity on one side of the passband, but less or none on the other side [8–15].In such ... with more poles and other configura-tions is feasible.10.2.2 Design ExampleFor the demonstration, a highly selective eight-pole microstrip CQ filter with theconfiguration of Figure 10.8(a) has...
