Low-frequency resonance is a bigger problem than high-frequency resonance in general industrial machines. This little-recognized distinction is crucial in determining the best way to correct it.

To correct oscillations in a machine,mechanical design improvements and electronic filters are typically employed.However, these solutions often deliver limited success. Engineers should ...

Do we really need another design tool for Sallen-Key filters? Aren’t there enough [i] [ii] [iii] [iv] [v] already? Obviously, you and I think that there’s something more to say on this topic, or you ...

Editor’s note: This article is a follow-up to the 2011 article, ‘Design second- and third-order Sallen Key filters with one op amp’ on EDN. Author’s Note: The author is revising this article to ...

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 ...
