What is the spectrum of a rectangular pulse?
1 The Rectangular Pulse. The Fourier transform of the rectangular pulse is real and its spectrum, a sinc function, is unbounded. This is equivalent to an upsampled pulse-train of upsampling factor L.
What is FFT phase spectrum?
The FFT function computes the complex DFT and the hence the results in a sequence of complex numbers of form . The amplitude spectrum is obtained. For obtaining a double-sided plot, the ordered frequency axis (result of fftshift) is computed based on the sampling frequency and the amplitude spectrum is plotted.
What is the Fourier transform of rectangular function?
Therefore, the Fourier transform of the rectangular function is. F[∏(tτ)]=τ⋅sinc(ωτ2) Or, it can also be represented as, ∏(tτ)FT↔τ⋅sinc(ωτ2)
