Opis

Modern high-capacity communication systems require filters with simultaneous good amplitude and phase responses. Selective Linear-Phase Switched-Capacitor and Digital Filters is the first coherent treatment of selective linear-phase switched-capacitor filters written by a leading international authority on the subject. Digital realizations of the same characteristics are also treated. In both cases, emphasis is laid on optimal low-sensitivity structures, a highly desirable attribute from the practical view-point. With the increasing interest in high-frequency switched-capacitor filters, the range of operation reaches a point where the phase response becomes a major design consideration, thus heightening the importance of this book. Selective Linear-Phase Switched-Capacitor and Digital Filters is an invaluable reference for electronic circuit design engineers and researchers as well as graduate students, and may be used as a text for an advanced course on the subject.
