active low pass filter with op amp
How do active filters work?
Active filters are also called active power line conditioners, and are able to compensate current and voltage harmonics, reactive power, regulate terminal voltage, suppress flicker, and to improve voltage balance in three-phase systems.
Active filters require a power source to operate, whereas passive filters don't.
The output of passive filters changes with the load, whereas active filters maintain their performance irrespective of the load connected.
Passive filters cannot apply additional gain to the signal, whereas active filters can.
What is used for a low pass filter?
The RC Low-Pass Filter
To create a passive low-pass filter, we need to combine a resistive element with a reactive element.
In other words, we need a circuit that consists of a resistor and either a capacitor or an inductor.
