How microcontrollers and single-board computers coordinate high-speed RF acquisition and generation. How SCPI and UART commands let simple controllers use advanced measurements without FPGA ...

This noise generator has an adjustable bandwidth and a consistent amplitude no matter what bandwidth is selected. When working on a recent Design Idea for an adjustable filter, I wanted to use an ...

Latency, bandwidth, and fidelity all matter when you’re chasing milliseconds.

Invincible Season 5 cast grows as Jack Quaid joins as Gravitator, an autodidact engineer whose gravity gun has a documented ...

Can an ESP32 detect people without cameras or motion sensors? Discover how Wi-Fi signal disturbances, CSI, and smart DSP enable real-time occupancy and mov ...

Audio frequency detection is the process of identifying the pitch or dominant frequency of a sound signal. Three common methods used are Fast Fourier Transform (FFT), AutoCorrelation, and ...

In a University of Kentucky laboratory, three small spacecraft stand-ins slid across low-friction air tracks, nudging and pulling one another without thrusters, propellant, or physical contact.

A clock is by its very nature a device for measuring time, and thus it moves forward at a constant rate. But how about in a ...

Let’s say you want to build a Nixie clock. You could go out and find some tubes, source a good power supply design, start whipping up a PCB, and working on a custom enclosure. Or, you could skip all ...

The “Wow!” signal is one of our best pieces of evidence for aliens, but researchers are building a compelling case for a more ...
