Analog filter design remains a cornerstone of modern signal processing, instrumental in a vast array of applications spanning telecommunications, instrumentation, and biomedical engineering. Recent ...

This application note presents the design and analysis of a passive LC filter. It briefly describes the use of measurement-based model for design and analysis, as well as the modeling filter behavior ...

EIM Technologies' Kickstarter campaign ended on April 16, 2025, reaching ~$108,000 in pledges. The book and associated kits can now be ordered from EIM directly, with details below. EIM used ...

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 ...

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 ...

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, ...

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 ...
