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.

Enter the integrated active EMI filter (AEF).1 This unique filter design has active circuitry for sensing of noise and then injecting a noise cancellation signal that will reduce the EMI (see figure).

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 ...

A new generation of wideband amplifiers and multipliers allows you to build state-variable active filters that operate beyond the kilohertz region into the megahertz region. Using these devices and ...

We’ve always been fascinated by things that perform complex electronic functions merely by virtue of their shapes. Waveguides come to mind, but so do active elements like filters made from no… ...
