The period of the signal x(t) = sin t + cos t is— 4 8
-
- 24π
- 6π
- 8π
- 12π
Correct Option: A
Given x(t) = sin | + cos | |||
4 | 8 |
Where, sin t/4 → x1(t)
cos t/8 → x2(t)
Fundamental period of
x1(t)= T1 = | = 8π | |
4 |
Fundamental period of
x2(t)= T2 = | = 16π | |
8 |
The period of signal x(t) is given as
= | = 0·5 | |||
T2 | 16π |
or T1 = 0·5
T2 = 8π
Hence, alternative (C) is the correct choice.
