ABSTRACT:
A ranking circuit operable in real time to rank a set of periodically changing sample values, having a series of sequentially clocked storage registers for sequentially storing the sample values, a series of corresponding first comparators for comparing each sample stored to the incoming sample, a summer for summing the outputs of the first comparators to assign an initial rank to the incoming sample, a series of rank registers for storing the initial rank value and a rank value corresponding to each sample in the sample registers, increment/decrement logic for adjusting each rank in the respective rank registers as each new sample is received, logic for effectively excluding a target sample from the ranking process, and logic for outputting a sample value of selected rank during each clock cycle. Optional logic for automatically adjusting the selected rank based on the relative amplitudes of the samples being ranked is also disclosed.
