Description

Noise reduction by filtering is the most commonly used method for improving signal-to-noise ratio. The increase in settling time however can be a serious disadvantage in some applications such as high-speed data acquisition systems. The nonlinear filter described here is a simple way to get a four-to-one improvement in settling time as compared to a conventional filter.
