In a simple RC low pass filter, the simplified transfer function comes out to:
1/(1+jwRC)
Solving for the root in the denominator, we see a pole exists at S=j/RC
This is also the w3db point where the magnitude of the transfer function starts falling.
Question: How is the w3db point also a pole? When you are making the bode plot, why does the magnitude not blow up at this point?
