I/O differentiates the source's data.
The output is proportional to rate of change of the input.
For example, if a source has the unit V, the output of the DIFF will have unit V/s.
The output range can be changed and fixed to user defined values.
The typical application of the Differentiate I/O is to use it as part of larger,
more complex mathematical operations.
The differentiate operation is very sensitive to noise, because noise in most cases has a higher frequency than the signal of interest.
To minimize the effect of noise, add a low-pass filter
processing block before or after the differentiate block.
In case you are measuring a periodic triggered signal, you can also use an average I/O
, which will give better results than filtering.
Common properties and actions
To control the behavior of the Differentiate I/O, several properties are available.
These can be accessed through a popup menu which is shown when the I/O is right clicked in the Object Tree.
The properties can also be accessed through its settings window which is shown when the I/O is double clicked in the Object Tree.
To open the Object tree, click the Show object tree button.
