Hi again!
I was reading the following link:
http://focus.ti.com/lit/ml/sloa088/sloa088.pdf
In page 16-12 (Figure 16-12) they are showing a first order
non-inverting low pass filter. I tried calculating the transfer
function and came up with the following:
Vo / Vin = (1 + R2/R3) / ( s*C1*R1 + 1 )
Their transfer function is:
Vo / Vin = (1 + R2/R3) / ( wc*s*C1*R1 + 1 ), wc = omega sub c (I think
this represents the cut off frequency).
My question is: how did they get wc?
Thanks!
