Explanation:
Solution
(1) Part (a)a waveform has a high frequency components compared to another waveform. the corresponding frequency components should be high.
So for the wave form a the corresponding frequency spectrum is (3)
(2) For part (b), waveform has three harmonics, the corresponding frequency spectrum is (1)
(3) The time domain waveform plot (c) is a sine wave but there exists a dc component.
Thus x[0] ≠0
For (c) the corresponding frequency spectrum is (5)
(4) For part (d) the corresponding frequency spectrum is (2)
(5) A sine wave is made of a single frequency only and its spectrum is a single point
For (e) the corresponding frequency spectrum is (4)
