Audio Low Pass Filter Circuit Diagram
An excellent noninverting Low Pass Audio Filter circuit diagram. 4 DB Gain from 300 to 1 KHz. 2 DB Gain at 2.5 KHz and 3DB down at 4.2 KHz. Input Impedance was tested using Multisim with a
load of 1K on both the input and the output with no changes in the Bode Plot so excellent for insertion between low impedance input/output stages.
