Hi, this is a problem I am trying to do:

So I found that at 3dB, V

and I wasn't sure if I should use real numbers or complex numbers, I did both, I'll show the real one:

V

Edit: I think I am suppose to find the total impedance by squaring each term in the denominator of R/(R+1/wc) and then square rooting it...I can then solve for f and I get +/- 2.08x10

Am I doing this completely wrong?

Thanks!

So I found that at 3dB, V

_{0}=0.7079V_{i}and I wasn't sure if I should use real numbers or complex numbers, I did both, I'll show the real one:

V

_{o}/V_{i}=0.7079=R/(R+1/wc)=Rwc/(Rwc+1)...I can solve for w, but this will only give one answer, when I use complex numbers I get 2 answers, but I'm pretty sure it's wrong...Edit: I think I am suppose to find the total impedance by squaring each term in the denominator of R/(R+1/wc) and then square rooting it...I can then solve for f and I get +/- 2.08x10

^{6}Hz, then the bandwidth would just be the positive value times 2....but I think this may still be wrong...Am I doing this completely wrong?

Thanks!
