If we have a LC high pass filter the transfer function H(s) becomes:

$$ H(s) = \cfrac{sL}{sL + \cfrac{1}{sC}} $$

If we solve for s to find a pole of the transfer function we get:

$$ s = j \cfrac{1}{\sqrt{LC}} $$

In the case of a sinusoidal input signal = $ s = j \omega \rightarrow \omega = \cfrac{1}{\sqrt{LC}} $

But in a case of a signal which may not be sinusoidal s can be a complex number and the result of this is that the pole exists at a complex frequency. But what physical meaning does a complex frequency have?
