Chapter 2, Problem 2.30P
Represent the function e(t) = 5 sin 31 At + 2 sin 44r as a discrete set of N = 128 numbers separated by a time increment of (UN). Use an appropriate algorithm to construct an amplitude spectrum from this data set. (Hint: A spreadsheet program or the program file DataSpect will handle this task.)

= 11
a) Derive the complex ambiguity function for x(t) and compare your result with the one
obtained in class.
b) Use MATLAB to compute the complex ambiguity function and compare it to part (a).
c) Now, consider the pulse
x(t) = sinc(Bt)
i) Derive the complex ambiguity function for x(t) and compare to the ambiguity function
of the rect pulse. Make your observations.
ii) Plot the ambiguity function using the mesh function and using the contour function.
iii) Use MATLAB to compute the complex ambiguity function and compare it to part (ii).
Find the local maximum and minimum values and saddle point(s) of the function. You are encouraged to use a calculator or computer to graph the function with a domain and viewpoint that reveals all the important aspects of the function. (Enter your answers as comma-separated lists. If an answer does not exist, enter DNE.)
