The Fourier Analysis –The Fast Fourier Transform (FFT) Method
https://www.electronics-lab.com/article/the-fourier-analysis-the-fast-fourier-transform-fft-method/
Introduction The Fourier Transform is a mathematical technique that transforms a time-domain signal into its frequency-domain representation. In other words, it decomposes a signal into its frequency components. The result is called the spectrum of the signal. Historically, the Fourier analysis concept developed slowly, from the Fourier series method 200 years ago up to the Discrete Fourier Transform (DFT) computing method today. Essentially, the Fourier decomposition was […]

Nowadays, almost all applications and devices provide speech recognition functionality, this makes the device look smart and user-friendly. Cloud plays an important role in integrating such features in hardware systems. But it increases the cost due to additional wireless components and complexity in the architecture of the device. Hence, an offline speech recognition feature can […]

FFTs and oscilloscopes: A practical guide
https://www.electronics-lab.com/ffts-oscilloscopes-practical-guide/
Arthur Pini @ edn.com published a guide on how to use FFT found in most modern oscilloscopes. The FFT (Fast Fourier Transform) first appeared when microprocessors entered commercial design in the 1970s. Today almost every oscilloscope from high-priced laboratory models to the lowest-priced hobby models offer FFT analysis. The FFT is a powerful tool, but […]
