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:
|
||
|
|

$\displaystyle f_{c} = \frac{1}{2\pi 100 * 0.00000001}$
|

|
|
$\displaystyle f_{c} = 159154.94 \approx 159.1kHz$
