Active Filters:
High Pass
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.
