This is
a collection of inverting and non-inverting active low 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 roll-off slope. |
