Using a resistor, a capacitor, and an inductor, you can build a simple notch filter as follows: What frequencies does it filter? The center frequency, also called the resonant frequency, around which this circuit will filter can be found as where L is the inductance of the inductor in H, and C is the capacitance of the capacitor in F.
