Analog filters are a critical component in all of PFI’s signal conditioning products. When properly implemented, an analog filter can separate a desired signal from noise and ensure adequate alias protection for sampling and A/D conversion.
Choosing the right filter for a particular application requires an understanding of filter response characteristics, which are derived from the mathematical relationship between input and output that forms the basis for filter design.
In the new white paper “Guide to Understanding Filter Specification Sheets”, Precision Filters explains the analysis behind PFI’s filter specification sheets, which summarize the response characteristics of their proprietary line of FLAT and PULSE designs.
