Zero-OffsetThe Zero-Offset step removes an offset from the signal. In the Input/Output tab selectExport offsets? which returns the offset signal as an output. The Input and OutputSignals graph, as seen in Figure 5.22, displays the input values versus the Zero-Offsetvalues.Figure 5. 21 Adding a Process StepFigure 5. 22 Zero Offset Step Set-up/Output Tab100
Set Setup Type to Manual, as seen in Figure 5.23.Thus, the user approximates the valuethat will offset the signal. The Offsets Table lists the offset for each input signal.Figure 5. 23 Configuration of OffsetFilterThe Filter step continuously attenuates unwanted frequencies from a time signal. Highlightthe Filter step in the left panel and select the Step Setup tab prompting a window such as theone seen in Figure 5.24. Under the Input tab, select the appropriate channel via InputSignal>> Voltage>> Voltage>> Zero Offset Data. Select the Configuration tab in theStep Setup prompting a window such as the one seen in Figure 5.24. Set Mode to IIRFilter, Type to Lowpass, and Topology to Butterworth. A lowpass filter attenuatesfrequencies greater than the lower cutoff. The lower cutoff is set to 2 Hz (0.5 sec) since allincident waves have lower frequencies.101
