A beginner’s guide to power of IQ data and beauty of negative frequencies – Part 2
Introduction and editor’s note This is a two-part series where DI authors Damian and Phoenix Bonicatto explore the IQ signal representation and negative frequencies. Part 1 explains the commonly used SDR IQ signal representation and negative frequencies without the complexity of math. This final part (Part 2) presents a device that allows you to play…
Tamron’s TAP-in Console: A nexus for camera lens update and control
Camera lenses were originally fully mechanical (and in some cases, still are; witness my Rokinon Cine optics suite). The user manually focused them, manually set the aperture, and manually zoomed them (for non-fixed-focal length optics, that is). Even when the aperture was camera body-controlled—in shutter-priority and fully auto-exposure modes, for example—the linkage between it and…
Demystifying AI And Machine Learning By Exploring GPUs, CPUs, TPUs
– Advertisement – Why is it absolutely vital to choose the right platform to train AI models? Well, sometimes, it can be a challenge with options like GPUs, CPUs, and TPUs.Performance, cost, and suitability, everything matters! An artificial intelligence (AI) enthusiast or professional often comes across a common question, “What kind of computing platform do…
A beginner’s guide to power of IQ data and beauty of negative frequencies – Part 1
Editor’s Note: This is a two-part series where DI authors Damian and Phoenix Bonicatto explore IQ signal representation and negative frequencies to ease the understanding and development of SDRs. Part 1 explains the commonly used SDR IQ signal representation and negative frequencies without the complexity of math. Part 2 (to be published) presents a device…
IndusVoltmeter: Smallest IoT Wireless Voltmeter with Wi-Fi
When I first thought about making a voltmeter, I wanted something small, easy to carry, and quick to use. I imagined it as a tool I could keep in my toolbox or use as part of a quick diagnostic kit. The goal was to create a tool that could measure voltages in two ranges (0-3.3V…
The 2025 CES: Safety, Longevity and Interoperability Remain a Mess
Once again this year, I’m thankfully reporting on CES (formerly also known by its de-acronym’d “Consumer Electronics Show” moniker, although the longer-winded version is apparently no more) from the remote comfort of my home office. There are admittedly worse places to visit than Las Vegas, especially given its newfound coolness courtesy of the Sphere (which…
How Connectors Enable the AI Revolution
– Advertisement – (Source: saicle / stock.adobe.com; generated with AI) Artificial intelligence (AI) is commonly described as computer programming trained to sense or learn about its environment from data, act accordingly, and then adapt its behavior based on the results. This has led to another innovation called machine learning (ML), in which the system’s performance…
Automotive insights from CES 2025
OEMs are shifting from installing black box solutions that specialized functions in the more conventional domain architecture to a zone architecture and a function-agnostic processing backbone where each node handles location-specific data. Along with this trend, there is a push towards optimizing sensor functions, fusing multimodal input data with ML for contextual awareness. Sensors no…
CES 2025: Approaches towards hardware acceleration
Edge computing has naturally been a hot topic at CES with companies highlighting a myriad of use cases where the pre-trained edge device runs inference locally to produce the desired output, never once interacting with the cloud. The complexity of these nodes has grown to not only include multimodal support with the fusion and collaboration…
Unconventional headphones: Sonic response consistency, albeit cosmetically ungainly
Back in mid-2019, I noted that the ability to discern high quality music and other audio playback (both in an absolute sense and when relatively differentiating between various delivery-format alternatives) was dependent not only on the characteristics of the audio itself but also on the equipment used to audition it. One key link in the…
