Third order filter

WebJan 31, 2011 · In a third-order filter, C 1 shunts much of this current to ground. While the high frequency current in a second order section (Figure 1) is simply Vin / R2, the current for a third order section (Figure 3) is reduced by the pole introduced by C1. The high frequency current from the input to the output of the third order section is (Vin / (R1 ... WebThen to bring the second order filters -3dB point back to the same position as the 1st order filter’s, we need to add a small amount of gain to the filter. So for a Butterworth second …
