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 ...

If you are in any way connected with radio, you will have encountered the low pass filter as a means to remove unwanted harmonics from the output of your transmitters. It’s a network of capacitors and ...

The input stage of an off-line power converter usually contains an LC averaging filter. A common practice is to damp the LC filter using additional reactive/dissipative components. In this article, we ...

(1) This article summarizes and analyzes the implementation methods of active damping corresponding to various virtual resistor placement positions, and provides suggestions for simplifying the design ...

SDRs have been a game changer for radio hobbyists, but for ham radio applications, they often need a little help. That’s especially true of SDR dongles, which don’t have a lot of selectivity in the HF ...
