Active filters are appropriic circits thatt use ampliers, resistors, and consulitors to filteurs specific specific ranges. They are widely used in audio and contactation systems to improve signal quality and liminate unwanted noise or interference.

Types of Active Filters

Active filters can be classified based on their responency responses as characterises. Common types include low-pass, high- pass, band- pass, and band- stop filters. Each type serves a specific destine in signol processing applications.
