The typical application of the SQRT I/O is to use it as part of larger, more complex mathematical operations.
Hint:
The SQRT-I/O can be used to calculate RMS values. Perform the following steps:
- Create a Multiply/Divide
- Create a Low pass filter
- Create a SQRT
- Drag your source onto the Multiply/Divide twice to calculate squared values of the source's data.
- Drag the Multiply/Divide onto the Low pass filter to calculate a running mean of the squares.
- Drag the Low pass filter onto the SQRT to get the RMS values.
- Optionally create a resampler and connect the SQRT to it to reduce the sample frequency.
Common properties and actions
To control the behavior of the SQRT I/O, several properties and actions are available. These can be accessed through a popup menu which is shown when the I/O is right clicked. For more information, see common properties and actions.
