In lectures I covered how a Schmitt trigger can be used in an RC circuit to determine the capacitance of the capacitor (Where the Schmitt trigger switches at 0.3V+ and 0.6V+). The equation given was that C = 1.2 R \ T (time period)(adsbygoogle = window.adsbygoogle || []).push({});

Does anyone know how to derive this or where it comes from? My lecture notes do not explain it.

Thanks :)
