What is the use of active power filters?
An active filter is a type of analog electronic filter that uses active components such as an amplifier. Amplifiers included in a filter design can be used to improve the performance and predictability of a filter, while avoiding the need for inductors (which are typically expensive compared to other components). An amplifier prevents the load impedance of the following stage from affecting the characteristics of the filter. An active filter can have complex poles and zeros without using a bulky or expensive inductor.
What is active devices?
An active device amplifies the signal by some value - such as an active filter using an OPAMP. A passive device does not provide any amplification - such as a passive filter network of inductors and capacitors.
What is The damping factor of an active filter?
good things
Can you drag Excel cell info while in filter?
You can drag while a filter is active, but only visible cells will have data put into them. So when the filter is removed, there may be gaps in the set of cells that have data in them. Any cells that were not visible when the filter was active will not have had the data dragged into them.
Why active filters so called even though uses passive resistors?
It has to have resistors but an active filter will alsol have an active device, usually an op-amp, while a passive filter has only passive components and needs no power supply.
What are the types of harmonic filters in ups?
Basically they are of 2 types 1) Active filter - For low voltage network 2)Passive filter
Is a saw filter an active component?
No, SAW filters are completely passive devices. You cannot get gain from a SAW filter, and they obey the rules of reciprocity (i.e. S12 = S21).
What is the advantage and disadvantages of active filter with amp?

How do you turn off specific filter?
To turn off a specific filter, first locate the filter option in your application's toolbar or settings menu. Click on the filter icon or menu to see the active filters. Then, uncheck or disable the specific filter you want to turn off, and apply the changes. Remember to save any settings if required to ensure the filter is successfully disabled.
How do you change oil filter on fiat panda 1.1 active?
To change the oil filter on a Fiat Panda 1.1 Active, first, ensure the engine is cool and secure the vehicle on a flat surface. Locate the oil filter, usually situated near the oil pan, and use an oil filter wrench to loosen and remove it, allowing any residual oil to drain. Before installing the new filter, apply a bit of fresh oil to the rubber gasket on the new filter, then screw it on by hand until snug. Finally, refill the engine with the appropriate type and amount of oil, and check for leaks around the new filter.
How can input impedance is made purely capacitive or inductive or zero or infinite?
By using a matching network, or filter (active or passive).
What is a hydrogen filter for a telescope?
A filter to let through certain wavelenghts of light. The wavelengths that Hydrogen is most active in. Other light does not get through so objects that "shine" in those wavelengths do not show in the image.
