Hello there,
Attached below is the question I am trying to solve.
(a) H(s) = 2sRC -- Is this correct? Does this mean the zero is at the origin? Is the '2' considered gain?
(b) I have no idea how to approach part b.. Help!
Same thing for the question below:
(a) H(s) = (1/RC)/s - considering R1C1 = R2C2 = RC
(b) I have no idea how to approach part b.. Help!
Thanks

For second image.. My attempt
(b) Putting s=jw => A(w) = (1/RC)/jw
converting to dB => A_dB = sqrt((1/RC)^2/w^2) = 1/RC/w
Substituting w = 100 and A_dB = 20 and letting C = 10nF => R = 50k ohm. Is this correct?
Thanks
