What is a "Boxcar Average"?

flatmaster

Hi, i'm Brand new to the Forums. I'm not sure this is the right forum. This may belong more under "experimental techniques" What is a "Boxcar Average"? I've seen it as both a mathematical function in some languages, and as a setting on my lock-in Amplifier. I think it may automatically throw out data points that are extremely far from your other data values.

Think I figured it out. It takes a 1D array of data and averages the last n data points to level out any wierd data. Is this right?

Yes. It's a rather simple and rather lousy filtering mechanism.
