Please say which statements are true and why, thanks!

[1pt] Consider the following periodic function ft), in which each horizontal grid 13 400ms and each vertical grid is 2 f(t) Which of the following statements are true? a. The phase of the dc component is not equal to 180 degrees. b. If the time scale of each horizontal grid were made half as long, then the amplitude of the 16th harmonic would stay the same. c. If the value of each vertical grid were made twice as large, then the amplitude of the 26th harmonic would change. d. If the function is shifted to the left by 400ms, then the amplitude of the 20th harmonic would stay the same. e. The amplitude of the 10th harmonic is not zero. f None of the statements above are true. Enter a single letter or a string of letters (abcde).

Explanation / Answer

a.true because DC doesn't have phase and frequency

b.true because amplitude doesn't change by changing time that is horizontal grid

c. False becuse The grid size doesn't decides the amplitude just it's a scale

D. False because its amplitude varies by shifting the signal

e. True because its have amplitude

f.false
