Wednesday, November 16 11:30am EST / 8:30am PST Click here to register. Several years ago, most of us were talking about 50 Billion connected devices by 2020. To get there we can’t just focus on the central hubs. The biggest challenges are the edge nodes, where we sense the environment, analyze locally, communicate what’s necessary, and […]

Gallery: Scenes from Texas Instruments’ power supply design seminar
Chip maker Texas Instruments has been touring the country with its one-day seminar covering topics in power supply design. A demo room is part of the proceedings. We…
Detecting the cliff effect with oscilloscopes
The cliff effect is a phenomenon that arises in digital as opposed to analog telecommunications, where reception is abruptly lost as signal strength fades or electromagnetic interference increases. The effect can be observed when traveling in a car that is equipped with satellite radio. As the signal source becomes eclipsed by patches of new vegetation […]

Basics of understanding power-factor and power-factor correction
In qualitative terms, power factor is a measure of the congruency of voltage and current ac waveforms imposed by a load on the power mains. Ignoring the relative…
FAQ: Ground rules: earth, chassis, and signal ground
In analog design, the relationship of a signal to ground is of fundamental concern (and can create issues in digital designs, too.) However, “ground” as a concept can…

FAQ: What are the benefits of 48-V distribution?
Mains-connected computational resources have been powered primarily by 12-V distribution feeds for decades. The 12-V distribution potential has been a convenient choice because it lets designers route power…
FAQ: What are the noisiest resistors?
Noise in circuits is always going to exist in one way or another. For those working with or designing electronics, noise can ride the working signal and can…

What’s the difference between a clock and a real time clock?
Microcontrollers act upon instructions a few bits at a time, collecting the next batch of bits at regular intervals. Those regular intervals need to have a regular cadence…
