Description
The PS RMS Estimator block measures the root mean square (RMS) value of a periodic signal.
A signal is periodic if it completes a pattern within a measurable time frame, called a period, and repeats that pattern over identical subsequent periods. The signal base frequency is the number of periods per second.
The block accepts a physical signal with one or more AC components present. It outputs an RMS value, where each frequency component is averaged over its time period.
Both the input and the output are physical signals. Untyped physical ports facilitate unit propagation. The output signal has the same physical unit as the input signal.
To obtain meaningful results, run the simulation for at least one full time period of the signal.

Programmatic Use: Add Block
To add the block programmatically, use the add_block function with one of these library block paths as the source.
"fl_lib/Physical Signals/Periodic Operators/PS RMS Estimator"
Example: add_block("fl_lib/Physical Signals/Periodic Operators/PS RMS Estimator","myModel/myBlock",MakeNameUnique="on")
For information about programmatic access to individual block parameters, see the Programmatic Use section of parameter descriptions on this page.
