High pass filters let through only signals with high frequencies and attenuate low frequency one.

Because high pass filters work exactly like low pass filters but in reverse, lets only do one example here:

Example:

Lets first calculate the cutoff frequency of this filter:

\displaystyle f_{c} = \frac{1}{2\pi 100 * 0.00000001}
\displaystyle f_{c} = 159154.94 \approx 159.1kHz
