Spectrum of a Sine Wave - MATLAB Tutorial for Beginners 2017

Spectrum of a Sinusoidal Wave - MATLAB Tutorial for Beginners 2017 A sine wave consists of a single frequency only, and its spectrum is a single point. Theoretically, a sine wave exists over infinite time and never changes. The mathematical transform that converts the time domain waveform into the frequency domain is called the Fourier transform, and it compresses all the information in the sine wave over infinite time into one point.
