A typical application of the Low pass filter I/O is to remove unwanted higher frequency noise from a measurement, which may negatively affect further operations on the measured data.
To control the behavior of the Low pass filter I/O, several properties are available. These can be accessed through a popup menu which is shown when the I/O is right clicked.
The Frequency property sets the cut-off frequency of the filter, the point where the amplitude of the signal is reduced by -3 dB. Several standard values are available, as well as a user defined setting.
A Gain property is available to apply an optional gain to the filter. Several standard values are available, as well as a user defined setting.
