This handbook is inspired by occasional questions from my stu dents
and coworkers as to how they can obtain easily the best network
functions from which they can complete their filter design projects
to satisfy certain criteria. They don't need any help to design the
filter. They need only the network function. It appears that this
crucial step can be a bottleneck to designers. This handbook is
meant to supply the information for those who need a quick answer
to a simple question of this kind. There are three most useful
basic standard low-pass magnitude characteristics used in filter
design. These are the Butterworth, the Chebyshev, and the elliptic
characteristics. The Butterworth charac teristic is maximally flat
at the origin. The Chebyshev characteristic gives equal-ripple
variation in the pass band. The elliptic character istic gives
equal-ripple variation in both the pass band and the stop band. The
Butterworth and the Chebyshev characteristics are fairly easy to
use, and formulas for their parameters are widely available and
fairly easy to apply. The theory and derivation of formulas for the
elliptic characteristic, however, are much more difficult to handle
and understand. This is chiefly because their original development
made use of the Jacobian elliptic functions, which are not familiar
to most electrical engineers. Although there are several other
methods of developing this characteristic, such as the potential
analogy, the Chebyshev rational functions, and numerical
techniques, most filter designers are as unfamiliar with these
methods as they are with the elliptic functions."
