What Are AC and DC Coupling?
We are often asked about AC and DC coupling. This is important to understand when working in the signal processing field. In terms of AC and DC Coupling, what is…
Why does Auto-Zero have no effect for IEPE sensors?
The Prosig P8000 Auto-Zero function is used to remove the DC content of a signal.
For example, if you have a sine wave that is ±5 volts about 0 volts it has no DC offset. But if you have a sine wave with ±5 volt amplitude about 3 volts, then it has a 3 volt DC offset. Below is an example of these two sinewaves.
Does The Signal Have A Gaussian Probability Density?
The PROB module in DATS for Windows provides, amongst other options, a probability density analysis. Also, the signal generation suite has a module, GENPRB, which generates a classical gaussian probability density curve (and others). How then may these be used to compare the probability density of our measured signal with that of a true Gaussian one. The method is quite straight forward and is a matter of scaling.
