Hi guys,
I'm newbie and have little knowledge on signalexpress. I'm using signalexpress for data logging process for my experiment. I want to do smoothing for my raw data graph. My supervisor said it can be done directly by using signalexpress but I still cannot figured out the way. I've searched online but there are all using labview.
Can someone help me to solve my problem? I really need help. I have no idea how to settle this anymore.
Thanks in advance.

What is your raw signal input type? I.E; temp, strain, analog voltage....
Most of the time you can add an Amplitudes and Levels step, then add the signals of interest to that step. The smoothing occurs within that A&L function. You can either view the signal in a graph or record it straight to file. Granted you wont get a timestamp when logging the data but I did find an equivalent sample rate calculation if you need it.
keep in mind, you'll need to add a A&L step to each signal "type" in your DAQmx Acquire step. For instance if you have Voltage and Custom Voltage w/ Excitation signal types, you will need to add two Amplitude and Levels step; one for each.
