Signal Analysis - NI-DAQmx 18.1 Manual https://www.ni.com/documentation/en/ni-daqmx/18.1/measfunds/siganalysis/
Signal analysis is the process of transforming an acquired signal to extract information about the signal, filter noise from the signal, and present the signal in a more understandable form than the raw ...

Z Indexing - NI-DAQmx 18.1 Manual https://www.ni.com/documentation/en/ni-daqmx/18.1/measfunds/zindexing/
Encoders typically use a third signal for Z indexing, which produces a pulse at fixed positions that you can use for precise determination of a reference position. For instance, if the Z index is 45° for ...
