A symmetrical lattice can be used to design a network of these objects with diagonally-crossed shunt elements; this expands on their ladder topology. Two opposing ones of these objects are added in the Linkwitz-Riley version of them. The Sallen-Key topology can be used to design these objects and calculate the poles and zeros of their transfer functions. These objects come in Chebyshev and (*) Butterworth varieties. Their ringing and quality factor can be read from Bode plots of their magnitude and phase, which show minus 3 decibel gain at a cutoff value but can never be an ideal step function. The simplest types of these things are created out of a resistor and a capacitor, and can come in notch, band-pass, and high-pass varieties. For ten points, name these structures which remove unwanted frequencies from a signal.
