HIGH PASS ACTIVE FILTER COLLECTION
 

This is a collection of inverting and non-inverting active high pass filter circuits.  I included one, two three, four and six pole filter circuits.  You can change the component value ratios shown to achieve any frequency cut-off you may need. The circuit does not specify an operational Amplifier.  The circuits should be used to select the needed resistor and capacitor components for a particular frequency knee and  slope.
