These forms are useful in the design of diplexers and multiplexers.

The gain of the passband therefore will vary between 1 and formula_5.

Also verifies simple passive LPF transfer function by means of trigonometric identity.

This is a technique used with radio receivers that are so close to a transmitter that it swamps all other signals.

There are two categories of digital filter the recursive filter and the nonrecursive filter.

The gain is then formula_15The phase is formula_16The group delay is formula_17The Taylor series expansion of the group delay is formula_18Note that the two terms in ω 2 and ω 4 are zero, resulting in a very flat group delay at .

The amount of attenuation for each frequency depends on the filter design.

An elliptic filter (also known as a Cauer filter, named after Wilhelm Cauer, or as a Zolotarev filter, after Yegor Zolotarev) is a signal processing filter with equalized ripple (equiripple) behavior in both the passband and the stopband.

The result is called an elliptic filter, also known as Cauer filter.
