Consider the function x(t) = sinc (t/2)
a. Draw the signal by hand in time for -10 < t < 10 sec.
b. Derive X(f) and draw it by hand for -3 C. Generate Matlab figures representing the functions x(t),x(f) within the same ranges of time and frequency. Explore different values of At and N to obtain a good match with your hand drawings.
d. Identify and discuss the discrepancies between your hand drawn signals and their representation in Matlab.
