Annoying speed bumps, which have become ubiquitous onroadways, force you to either slow down or find a way aroundthem. While driving recently, I needed to negotiate one ofthose bumps, and doing so ...

This file type includes high resolution graphics and schematics when applicable. When designing filters, engineers very often need to know what the filtered value at the output will be. This is ...

As you may have guessed given our name, we do love hacks around here, and this one is a great example of making some common, everyday things work in uncommon ways. [Nathan] sent in his hack to detect ...

This article is part of the Ideas for Design Series: Vol. 3, No. 9. Many communications and sensor applications require a bandpass filter with wide bandwidth. This filter typically requires precision ...

When we do textbook analysis, we tend to ignore the real-world concerns for the sake of learning. So, a typical theoretical voltage divider is simply two resistors. But if you examine a low-pass RC ...

Active filters are ubiquitous in electronic design today, performing signal-frequency manipulation and conditioning for audio, IF (intermediate frequency), and digital-signal processing. The success ...
