Summary[edit]

Detail of Image:EllipticGain8.png, which is an image of the log of the absolute value of the gain of an 8th order elliptic filter in complex frequency space (s=σ+jω) with ε=0.5, ξ=1.05 and . The white spots are poles and the black spots are zeroes. There are a total of 16 poles and 8 double zeroes. What appears to be a single pole and zero near the transition region is actually four poles and two double zeroes as shown in the expanded view below. In this image, black corresponds to a gain of 0.0001 or less and white corresponds to a gain of 10 or more.
