 [Qucs-help] question to root mean square value From: Meisinger Markus - 2006-02-28 07:55:50 ```Hello! So far I simulated a few "larger" circuits with qucs. In conclusion I can say that it is a really powerful tool and I am very very glad to have it ;-) ! Now I have a problem developping a flying back converter circuit since I have not found any possibility to calculate a root mean square value out of a signals trace. This is necessary for the calculation of a booster capacitor or e.g. the power supply which is connected to the circuit. Thats why I would like to know wheather there is any possibility to calculate a mean square / root mean square value out of a recorded voltage-, current- or equation - measurment? Thank you very much for your answer! Best regards Markus Meisinger ```

Simply place an equation on the schematic. E.g. Bla="sqrt(avg(node1.Vt^2))", that what you mean? Stefan. ```
