Active Filters (216) – Page 9

Active filters are electronic filters that use active components such as operational amplifiers to achieve desired filtering characteristics. They provide precise control over frequency response and are used in applications requiring high-performance signal filtering, such as audio processing, communication systems, and instrumentation. Active filters offer advantages over passive filters, including gain adjustment and the ability to implement complex filter designs. Their ability to provide accurate and flexible filtering makes them essential for high-quality signal processing.
