In this Design Idea (DI), the classic Schmitt-trigger-based RC oscillator is “hacked” and analyzed using the simulation software QSPICE. You might reasonably ask why one would do this, given that ...

Abstract: A reconfigurable mode-locked optoelectronic oscillator (OEO) based on a directly modulated distributed feedback laser diode (DFB-LD) is proposed and experimentally demonstrated. In the ...

How it started: a simple repair job on a Roland drum machine. How it ended: a scratch-built FM drum synth module that’s completely analog, and completely cool. [Moritz Klein]’s journey down the analog ...

This study presents a portable near-infrared laser heterodyne radiometer specifically designed for measuring the column abundance of atmospheric carbon dioxide (CO₂) in the Taiyuan area. The ...

In which we embark on a quest to forge a precise triangle wave, and use that to help set a gold standard for fake sine waves. How well will we fare? A while ago, I needed (or wanted) a pocket-sized ...

In recent years, transverse mode instability (TMI) has been widely observed in fiber laser amplifier systems. The transverse mode instability phenomenon in fiber laser oscillators is less studied.
