Filters - Active

Active filters are essential components in electronic circuits designed to enhance signal quality by filtering out unwanted frequencies. Unlike passive filters, which rely on resistors, capacitors, and inductors, active filters utilise amplifying devices like operational amplifiers to achieve greater performance and flexibility. They are crucial for applications requiring precise signal processing and noise reduction, making them invaluable in both consumer electronics and industrial systems. They provide superior performance compared to passive filters by offering adjustable cutoff frequencies, gain control, and the ability to handle lower impedance loads.
