Using a copy of [SPICE] a free circuit simulation application, I have created several sine wave sources and summed ... form of a Fast Fourier Transform (FFT). For this demonstration I left the ...
In audio signals, the sinusoidal waves are created by sound vibrations and may be at varying amplitudes and phase as well as frequency. To simulate this variety, the utils.make_waves function provides ...
This project is a simple Python program that computes the Fast Fourier Transform (FFT) of a .wav file or a sine wave defined by the user. Users can define the frequency, phase, sample frequency and ...
The chapter examines the spectrum of a sine wave using Simulink library blocks ... The spectrum calculations using a fast Fourier transform (FFT) have demonstrated the need to utilize a window ...

The representation of a PERIODIC sound or WAVEFORM as a sum of Fourier components (i.e. pure SINUSOIDAL WAVEs). According to the FOURIER THEOREM, periodic sound may be shown to consist of SINE WAVEs ...
Alan demonstrates the relationship between the time waveform and the FFT spectrum. He modulates a 25 Hz sine wave with another sine wave, resulting in sidebands in the spectrum. This modulation, the ...
