Power systems dedicated to next-generation high-performance blade servers, datacenters, storage and communication infrastructure systems are a group that “feels the need--the need for speed!” ...

Although it dates back to the early days of the Marconi Company in the 1920s, the Franklin oscillator has remained a relatively obscure circuit, its memory mostly kept alive by ham radio operators who ...

In this video I’m showing how I’ve built a very simple battery backup circuit for my home alarm system. The circuit charges a 12v lead acid battery and in an event of a power loss, it transfers the ...

Ceramic resonators and filters occupy a practical middle ground in frequency control and signal conditioning, offering designers cost-effective alternatives to quartz crystals and LC networks. Built ...

"Learn how to set up and analyze an RC circuit using the PhET Simulator! In this tutorial, I’ll guide you through the step-by-step process of building a simple resistor-capacitor circuit, explaining ...

Abstract: A family of LC ladder circuits is analyzed with an abstract model for growth in a diverse set of systems, with possible applications to biological organisms, self-assembly of nanostructures, ...

Abstract: This tutorial will go through the fundamentals of LC oscillator and LC VCO design, such as basic phase-noise theory, design for low power, low phase noise and, large tuning range (including ...

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 ...
