このプロジェクトは、Arduinoを使用して筋電位（EMG）信号を取得し、FFT（高速フーリエ変換）を行って周波数成分を分析するものです。EMG信号の周波数分析により、筋肉の活動状態や疲労度などを評価することができます。

Yukikaze is a physical output device for the spectrum analyzer. This device gives the computer the means to display a continuous amount. Mechanism This device is composed of two parts. 1.Case unit ...

Upload the code to ESP32 using Arduino, or any other method you prefer. Pay attention on the problems with the analogRead function described in the documentation. Use the sketch in sketch_sample_rate ...

However, their spectrum analysis abilities are lacking. While these scopes do have a Fast Fourier Transform (FFT) function, it’s limited and nearly useless for RF.

This paper belongs to a set of efforts aimed to improve the education of engineering in electronic and telecommunications, based on virtual equipment. It stand on a previous work called Networking ...

Although a spectrum analyzer exhibits better dynamic range and less distortion, the digital oscilloscope FFT provides a cost-effective, space-saving alternative.

With an off-the-shelf LCD, this mess of wires and boards turns into an auto-scanning spectrum analyzer that’s also able to put video from a drone onto a screen.
