Theory and Design Data for Uniformly Dissipative, Doubly Terminated Bandpass and Lowpass Filters

摘要

Design data are given in the form of curves of the normalized parameters for the exact design of uniformly dissipative, doubly terminated bandpass and lowpass filters with Butterworth, Chebyshev, or Bessel transfer functions having two, three, four, or five poles. For the Chebyshev filters, pass-band ripples of 0.001, 0.01, 0.03, 0.10, 0.30, and 1.0 dB are included. Curves are also given for gain, phase, group delay, and transient response, most of which are not readily available elsewhere. A complete theoretical development of the design is given, and the solution for the five-pole case is apparently new. Multiple solutions for the design parameters are discussed in the light of modern network synthesis, and the correspondence between the two is established. (Author)
