MEDIAN FILTERS

ITC/USA 2006 Conference Proceedings / The Forty-Second Annual International Telemetering Conference and Technical Exhibition / October 23-26, 2006 / Town and Country Resort & Convention Center, San Diego, California / Most modern digital filtering is done by taking the average (mean) of a signal or some weighted
average. Another method is to use feedback, which more closely resembles how analog filters
with feedback operate. In the case of low pass filters, all these methods tend to give a trade off
in getting the signal to pass while attenuating the higher frequency noise. An alternative is to use
a median filter, which selects the mid value of a group of points. While this is not as
computationally simple as other filters, it allows for the attenuation of noise while allowing
sudden changes in signal level to pass thru unaltered. This paper discusses the characteristics of
median filters and methods of implementing them.
