Today I am experimenting with a single chip Universal Active Filter, in this case I made a small PCB for the UAF-42 from Texas Instruments. I chose this part in particular as it facilitates setting ...

Consumer requirement for fewer wires connecting their home entertainment systems is driving up the demand for wireless active speakers. In order to achieve the best audio quality from high end active ...

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 ...

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 ...

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 ...

Sponsored by Texas Instruments: A unique electromagnetic-interference reduction feature facilitates high-power-density designs while shrinking their footprint and cost. Since power density is a ...

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 ...

Schaffner is aiming at active front end (AFE) drives and active in-feed converters (AIC) with a range of three-phase LCL mains filters. Called FN 6840, they come in a variety of specifications and are ...
