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 ...

APUスペクトラムアナライザは、様々なFFT設定オプションをサポートする無料のスペクトル解析ツールです。FFTウィンドウの種類（Rect、Hann、Hamming、Blackman、Kaiser）とサイズ（64～65536）をニーズに合わせて調整できます。履歴サイズを調整してスペクトルを ...

KISS FFT converts a time-domain signal (a series of samples from a microphone, ADC, accelerometer, etc.) into the frequency domain, revealing which frequencies are present and how strong each one is.

Everyone’s a critic, but it’s hard to argue with success. And that’s exactly what [agp.cooper] has with his ATtiny85-based spectrum analyzer devices. The “normal” way to build a spectrum analyzer is ...

This project implements a custom fixed-point FIR filter in SystemVerilog and integrates the Xilinx FFT LogiCORE IP to build a small spectral analysis pipeline.

The analysis of electrical signals, otherwise known as signal analysis, is a fundamental challenge for virtually all electronic design engineers and scientists. While it provides valuable insight into ...
