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 ...

Active band pass filters (BPF) attenuate frequencies below and above a range of frequencies (i.e., the bandwidth or passband of the filter). Any signal with a frequency within that band pass range ...

Active filters are electronic filers that use active components such as amplifiers. Their output is not attenuated with respect to the input voltage. The amplifier—normally an operational ...

What do you really get using a supplier tool for an multiple feedback (MFB) low pass active filter? Let's continue the quest for the best results using the example designs from Part 1. In this online ...

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 ...

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 ...

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, ...

The state variable active filter (SVAF) is an active filter you don’t see mentioned much today; however, it’s been a valuable asset for us old analog types in the past. This became especially true ...

As electrical systems become increasingly dense and interconnected, mitigating EMI is a critical system design consideration for engineers. With innovative developments from Kilby Labs, TI's research ...
