Abstract :
The threshold gate is a very good candidate in the realization of order statistic filtering. In this paper, a simple procedure is developed to determine the circuit parameters for a set of output-wired CMOS inverters in order to implement threshold functions for order statistic filtering. Weighted and nonweighted order statistic filters in either binary or integer domain can be easily realized in similar architectures. An incremental scheme is also proposed to construct threshold gate networks for general or multi-stage order statistic filters
