A multiple feedback is a very popular feedback topology used to build active filters using OPAMP. In this video we will learn how to make such a bandpass filter using this topology using opamp as active component. This circuit can be used for mid range woofers, 200 - 2000 Hz. We will see the circuit, printed circuit board PCB using Kicad, and simulation using Multisim online. Finally we will also see how the actual hardware works with the help of a DSO ( Digital Storage Oscilloscope ) and will compare the simulated results and the actual hardware.
