So let’s take a quick look at how varying frequency changes the performance of a circuit. The circuit above has a capacitor, inductor, and resistor in series. We’d like to know what the output, Vout, is as a function of frequency.We can get Vout just as we’d normally do with a voltage divider. Since we’re dealing with inductors and capacitors, frequency will show up here.We can manipulate this a little to get it into the standardized form we looked at earlier and make the substitution of s for jω. We’re left with an equation that describes the behavior of Vout with regard to frequency. -- source link
