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...
