Sinc pulse shaping is commonly used in digital communication systems to achieve ideal Nyquist pulse shaping, minimizing intersymbol interference (ISI).
The sinc function is defined as: \( \text{sinc}(t) = \frac{\sin(\pi t)}{\pi t} \)
Explanation:
The sinc function arises as the inverse Fourier Transform of a rectangular function in the frequency domain.
In other words, if the frequency spectrum is a perfect rectangular shape (ideal low-pass filter), its time-domain representation is a sinc function.
Conclusion:
Correct Answer: Option 4) rectangular
