If you're responsible for maintaining quality power at a commercial facility and you've got a problem with harmonics, your best bet is to install a series of active filters. Opting for such filters ...

In the last edition of Don’t Fear the Filter, we built up two examples of the simplest and most-used active filter of all time: the two-pole Sallen-Key lowpass. This time, we’re going to put two of ...

An easy way to conceptualize active filters is thinking about audio speakers. A speaker crossover has a low-pass, high-pass and band-pass effect breaking a signal into three components based upon ...

In a world of digital electronics, there are still necessary functions for analog circuits, especially filters. When real-world signals are digitized or synthesized, for example, analog filters are ...

The EPCOS PQSine™ series of active harmonic filters from TDK Corp. are designed to optimize power quality. The modular filter systems are designed for 3-phase networks with and without neutral ...

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 ...

The SLAC National Accelerator Laboratory, Menlo Park, Calif., is home to a 2-mile-long linear accelerator — the longest linear accelerator in the world. This multipurpose laboratory for astrophysics, ...
