Hello,
I'd like to know how to get Cs and Rs.. Here I've substituted arbitrary values for both Rs And Cs; only R1 is set at 100Ω[ I varied this from 10Ω - 150Ω ] . So from ltspice I got an output like this
But if I hook this circuit up to an osci [with Cs and Rs unknown] I get this.
Any idea?
From that graph, I kinda got Cs through this - which is just a magnified pic of the blue output slope - by measuring the tau = 63.2% x Uoutput (max) and then Cs = tau/R1 = 0.380nF. How to get Rs? Not quite certain here. Think I'm doing it wrong somewhere.
Thanks!
