All circuits, analog or digital, have characteristics dependent on the values of their component parts. Invariably, these parts are non-ideal in many ways. Even their most fundamental characteristics, ...

Editor’s note: I am proud to bring you this article authored by both Collin Wells, Applications Manager, General Purpose amplifier products, Texas Instruments and Gustaf Falk Olson, Field Applications ...

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 nothing but ...

Previously on The Filter Wizard (“Simulate Circuits in a Spreadsheet with some ‘Ladderal Thinking’ “), we saw how to use a spreadsheet such as Excel to calculate the frequency response of a filter ...

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 ...

We bet when [devttyS0] made his latest video about RF filter design (YouTube, embedded below), he had the old saying in mind: in theory, there’s no difference between theory and practice, but in ...

What are the main generators RF EMI? How to implement electromagnetic and electrostatic shielding. Passive and active filtering for RF designs. Suppressing RF EMI will require multiple solutions that ...

Residential and commercial circuit breakers face three major challenges: detecting arc faults reliably, reducing false trips ...
