(a) Write a functional description of the time-domain energy signal in Figure E.44 as the product of two functions of t.
(b) Write a functional description of the frequency-domain signal as the sum of two functions of f.
(c) Find the numerical values of a and b.
(a) 
(b) 
(c) a is at the first positive-frequency null of (f-1) which occurs at f=2 . Therefore a = 2.
The phase values are all either ?/2 or - ?/2 or because of the (j/2) factor. Therefore b= ?/2.
