Designing a 5 th Order Low-pass Chebyshev Filter
Omar X. Avelar, Omar de la Mora, Diego Romero · 2009
Electronic filters must be divided in two main branches, active or passive, then they can be categorized by topology (if active), type (behavior) and order. The topology mainly describes the method the circuit will be built physically by arranging electronic components in particular ways, type behavior (Fig. 1) describes the frequency response or time domain characteristics of the filter and the order primary depends on the transfer function. For example, one can build a 5 order Chebyshev or Butterworth filter with a Sallen-Key topology, while someone else may choose to implement the same on a different topology such as multiple feedback.
