Question 2 (25 points, IQ Modulation): A wireless system uses the signal constellation given in the diagram in Fig. 2. The dotted shape represents a square. (a) (5 Pts.) Write down all the passband signals. Also determine how many bits are sent per each passband signal? (b) (5 Pts.) For average energy of 1, what constant coefficient should we multiply the passband signals with? (c) (5 Pts.) If the signals are sent every $T_b$ = 1 usec, determine the baud rate and the bit rate for this system? (d) (10 Pts.) In a noisy environment, the constellations at the receiver side will be in different parts of the diagram.

Write a Lisp function first-sat that takes two lists and a function foo as arguments. Function foo should take two arguments and return a Boolean (t or nil). The result of a call to first-sat should be a list containing the first pair of arguments that satisfies (returns true) from foo. For example: (first-sat '(1 4 3 5) '(2 5 1 4) #'(lambda (x y) (> x y))) Note that #' is the same as (function ... ) so (first-sat '(1 4 3 5) '(2 5 1 4) (function (lambda (x y) (> x y)))) returns (3 1).
