The Zoom FFT is interesting because it blends complex down conversion, lowpass filtering, and sample rate change through decimation in a spectrum analysis application. The Zoom FFT method of spectrum ...
(1)、(2)に引き続き、今回はフィルター処理前後のパワースペクトル表示を追加してみます。 毎フレーム描画をすると動作が重くなるので、タイマー割り込みを使って0.5秒毎に表示をします。レイテンシーが大きくならないよう、フィルター処理と ...
ERC Convener Assignment – AM Audio Demodulation. This is a part of the ERC Convener Assignment. It involves demodulating a noisy AM (Amplitude Modulated) audio signal using MATLAB. The steps include ...
Abstract: The estimated accuracy of phase and frequency of all phase FFT spectrum analysis and its correction techniques are high[1-3], for its perfect characteristic of inhibiting the spectrum ...
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 ...
Abstract: Accuracy, speed, and dynamic range, are important considerations, among which tradeoffs are typically made for a given measurement. We present that FFT spectrum analysis is inherently less ...
The proposed device leverages the computational capabilities of MATLAB to provide a portable and efficient means of fracture detection. By harnessing sound waves, which are safer than ionizing ...
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 ...
