Abstract
An analog feedback rank order filter electronic circuit for receiving a number N of analog input signals (V.sub.1, V.sub.2, . . ., V.sub.N) and reproducing at its output (V.sub.o) the magnitude of that one of the input signals having a magnitude which is the K.sup.th largest among the magnitudes of the N input signals, K being an adjustable rank parameter in the range of 1 to N, comprising: N comparator subcircuits, a summation subcircuit, an integrator subcircuit and means for generating a control signal whose magnitude selects the desired rank parameter K.
