Electronic components are strictly functional objects: their appearance is determined by the function they’re meant to fulfil. But that doesn’t mean there’s no beauty in them. In fact, a whole ...

In theory, synchronous clock multiplication is an easy task. A simple PLL with two digital dividers—one inserted just after the VCO (voltage-controlled oscillator) and the second one placed directly ...

If there’s no circuitry on a printed circuit board, does it cease being a “PCB” and perhaps instead become just a “PB”? Call them what you will, the fact that PCBs have become so cheap and easy to ...

A small portable device featuring timer, clock, and calendar functions, equipped with a simple and functional interface and a truly long battery life.

This accurate one-pulse-per-second clock is made with a few common parts and driven from a 50 or 60 Hertz mains supply but with no direct connection to it. A beep or metronome-like click and/or a ...

Clocks are the heartbeats of embedded systems, providing timing references and synchronization between components, subsystems, and entire systems. Incorrect clock signal amplitudes and timing can ...

What’s a multiservice router/ switch? Multiservice routers and switches are network devices that support multiple switching and routing protocols, typically adding Multiprotocol Label Switching (MPLS) ...

OK, here's a little electronics mystery. I have an old (2000s) wall clock in my bedroom that I had to take apart just now because a battery leaked in it (dang Duracells....). The clock takes two AA ...

Almost all living creatures have an endogenous clock that enables them to adapt their behavior and body functions to the natural rhythm of day and night. This so-called circadian rhythm is controlled ...
