ANALOG FEEDBACK RANK ORDER FILTER

摘要

An analog feedback rank order filter electronic circuit for receiving a number N of analog input signals (V1, V2, ..., VN) and reproducing at its output (VO) the magnitude of that one of the input signals having a magnitude which is the Kth 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 generat-ing a control signal whose magnitude selects the desired rank parameter K.
