Active filters and advanced signal processing techniques are at the forefront of modern electronic system design, enabling precise manipulation of analogue signals for a variety of applications. Owing ...

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 ...

Digital signal processors (DSPs) continue to receive a great deal of attention in new product design. For example, digital filter design reflects the importance of understanding and using this ...

I have a couple of friends who love active filter design. One is Martin Cano, who did the math behind National Semiconductor’s WEBENCH active filter design tool. Another active filter nut I got to ...

A new IC-based approach to EMI filtering in ac-dc power subsystems dramatically cuts inductor size and offers other benefits as well. The nature of the EMI problem in ac-dc supplies and its ...
