This function calculates the rms value of a square wave voltage. It is assumed that the pulse duration ( ti ) and the Pause ( tp ) have the same length.

The rms value is defined as a DC voltage value with the same thermal effect as the specified pulse voltage.
The rms value is for square-wave voltages whose pulse duration (ti) and pause (tp) have the same length:
\(\displaystyle U_{rms}=\frac{U_p}{\sqrt{2}}\)
The mean value of the voltage is half the peak voltage.
\(\displaystyle U_m = \frac{U_p}{2} \)
In the case of a symmetrical square-wave alternating voltage, the rms value is equal to the peak value
\(\displaystyle U_{rms}=U_p\)
The mean value of a symmetrical square-wave alternating voltage is always 0 volts.
\(\displaystyle U_p\)
Peak voltage
\(\displaystyle U_{rms}\)
Effective voltage
\(\displaystyle U_m\)
