where a0 = b0 = ?r2, a = ??, ? = 1/q, ?r is the cutoff frequency of the filter, ? is the damping coefficient, and q is the Q-factor of the filter. The filter contains adders, multipliers, time delay elements, and additionally, two circuits connected in series, each of which contains an input amplifier, an adder, and a time delay element.
