Active filters are vital in modern electronics; every data acquisition systems need them for bandwidth-limiting signals before ADCs as anti-aliasing filters, or after DACs as anti-imaging filters. Instrumentation also relies on them for accurate signal measurements.
Active filters are used for cutoff frequencies that range from sub -1Hz to 10MHz, where passive filter designs would require prohibitively large component values and sizes. Their design and verification can be tedious and time consuming.
The filter design tool from Texas Instruments lets you design, optimise, and simulate complete multi-stage active filter solutions within minutes.
