Design and implementation of an analogue median filter for real-time processing
B. D. LIU, C.S. Tsay, C. H. Chen · International Journal of Electronics · 1993
A new architecture is proposed for analogue median filters; without the high accuracy reference voltage, high speed analogue summer, and linear sawtooth wave generator; therefore it is easy to implement by VLSI technology. The features of this architecture are modular, regular, locally connected and expansible. The throughput is independent of the window size and the hardware complexity is linearly dependent on the window size.
