Answer to Problem 1RQ
The correct option is
Explanation of Solution
Formula used:
Consider the general form of Fourier transform of
Calculation:
The Fourier transform is defined as, it is an integral transformation of
Refer to Table 18.2 in the textbook for Fourier transform pairs.
Option (a):
Substitute
Option (b):
Substitute
Option (d):
Substitute
Therefore options (a), (b) and (d) has Fourier transform and option (c) does not have a Fourier transform.
