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 ...

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 ...

These days, streaming services are a great way to listen to music or podcasts on your computer or on the go. However, they lack one feature of the MP3 players and streamers of old: visualizations!

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.

Everything you wanted to know (but were too afraid to ask) about using the MSGEQ7 audio spectrum analyzer chip. I’ve talked about using the MSGEQ7 Spectrum Analyzer chip in several columns over the ...

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 ...

No instrument, whether in the time or frequency domains, is suitable for all use cases. Signal/spectrum analyzers shine for ensuring standards conformity. Oscilloscopes tend to be more versatile, ...
