Every machine has its own way of communicating with its operator. Some send status emails, some illuminate, but most of them vibrate and make noise. If it hums happily, that’s usually a good sign, but ...

In earlier articles, we looked at the basics of fast-Fourier transforms (FFTs) and how to set up an FFT on a modern digital oscilloscope. In this post, we’ll take a brief look at what that modern ...

Modern pulsed radar systems use advanced waveform and modulation characteristics to obtain greater range resolution, enhanced clutter suppression and superior target recognition. Specifically, ...

Radio seems to be an unofficial theme for The Hackaday Prize, with a few wireless frameworks for microcontrollers and software defined radios making their way into the quarterfinal selection.

Real-time spectrum analysis of audio signals using FPGA-based Fast Fourier Transform implementation on the Zynq-7000 SoC platform. This project implements a real-time audio spectrum analyzer using the ...

With the ever-expanding adoption of wireless in embedded systems of all types, there’s no question that having spectrum analyzer capability in an oscilloscope is a time-savings convenience for ...

There are many ways to look at the world, and many ways to look at electronic signals. Many fundamental instruments, such as voltmeters and oscilloscopes, use a time-oriented approach. They provide ...
