Abstract :
Diagnosing noise problems in data acquisition (DAQ) circuitry can be difficult and frustrating, especially the first time you encounter a problem. Fortunately, when dealing with data acquisition, we tend to see a lot of the same recurring problems, so solutions come relatively easily. A simple but frustrating problem that sometimes crops up is crosstalk between channels. This article presents several examples and solutions to the crosstalk problem.
