What is the Fourier transform of a sine function?

Therefore, the Fourier transform of the sine wave is, F[sinω0t]=−jπ[δ(ω−ω0)−δ(ω+ω0)]

How to plot Fourier transform of sine wave in MATLAB?

f = -fs/2:fs/(N-1):fs/2; z = fftshift(fft(x)); subplot(2,1,2); plot(f,abs(z));

What is Fourier transform of window function?

A window function provides a weighted selection of a portion of a time waveform for fast Fourier transform (FFT) analysis. It is generated by multiplying the original time waveform by a user-defined window function of some width. In this case, width equals two times the number of analysis lines.
