WebNow we'll sample this same/common signal in 4 ways: 100 Hz sample rate. 29 Hz sample rate. 29 Hz sample rate, and add a 1g bias. 15 Hz sample rate. Here's a plot of 2 seconds worth of this data: Now let's calculate the metrics for this exact same signal, but with 4 different sampling characteristics: Data Set. WebOne quick way to see the discrepancies between these PSDs is to take a look at the average vibration level defined by gRMS. Our "standard" is pretty spot on for the Ford F150, although it is a little high on the A320 which I'll highlight later why. ...
