Obtaining valid data from a measurement system requires properly designed analog filters to eliminate noise, preserve the integrity of the in-band data of interest, and provide adequate alias protection. Precision Filters offers two proprietary filter designs that can be selected via software control to optimize filter response for a given set of measurement criteria. The flat and pulse mode filters are complementary, accommodating the design tradeoff between a flat amplitude response and a linear phase response.
In a new article, Precision Filters explains the differences between the flat and pulse mode filter characteristics, along with comparisons to conventional filter types. Representative examples that illustrate filter properties are given using simple test signals. The amplitude, phase, and transient response of each filter are shown and discussed.

From the laboratory to the test cell, Precision Filters' programmable filter/amplifier system line-up has you covered. Choose from the high-density modular 28000 system that packs up to 128 channels of anti-alias filter/amps in a single chassis, the convenient 16-channel PF-1U rack mount filter/amplifier system, or the compact PFA-2 two-channel desktop unit. We even off programmable filter modules for NI's™ popular cDAQ™ and cRIO™ format.
