This audio spectrum analyzer utilizes an ARM7 LPC2138 microcontroller to create an FFT algorithm while performing digital signal processing without the use of special DSP processor. This audio ...

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 ...

You can create a release to package software, along with release notes and links to binary files, for other people to use. Learn more about releases in our docs.

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.

Many of today's digital oscilloscopes include fast-Fourier-transform (FFT) capability for frequency-domain analysis. This feature is especially valuable for oscilloscope users who have limited or no ...

A high-performance, real-time spectrum analyzer implemented on FPGA using VHDL, capable of performing instantaneous spectral analysis of 1D signals through FFT computation. This project implements a ...

Darren McCarthy, technical marketing manager at Rohde & Schwarz (R&S), elaborated, “The trade-off between a swept-tuned and an FFT-based analyzer can be seen in the speed of performing a spectrum ...
