This equation computes the angular frequency term (ω0) of the transfer function for a unity gain low pass filter implementation of the Sallen-Key topology.  This electronic filter is a special case of a second-order unity gain filter version of the voltage-controlled voltage-source (VCVS) topology.

ω0 is derived from the resistances and capacitances (R1,R2,C1,C21) of the filter (see picture).
