Active filters are ubiquitous in electronic design today, performing signal-frequency manipulation and conditioning for audio, IF (intermediate frequency), and digital-signal processing. The success ...

To build active filters for high-frequency RF applications, designers may construct discrete designs using op amps and passives. When matched filters are required, this can become costly, as it ...

Brick wall filters are desirable in a number of audio, instrumentation and data acquisition applications. Creating these filters in the analog domain presents many cost and implementation challenges, ...
