We present a theoretically consistent method for measuring topological charge using an inverse renormalization group transformation. We show that, using a fixed point action, the action of smooth configurations with non-zero topological charge is greater than or equal to its continuum value $8π^2/g^2$.uufiles plain latex mss, epsf figures appended as .eps filesHigh Energy Physics - LatticeInstantons and Fixed Point Actions in SU(2) Gauge Theorytext
