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.
