1.
Select the best answer regarding your observation
a. both s(t) and b(t) appear as identical sine waves | ||
b. both s(t) and b(t) appear as identical cosine waves | ||
c. s(t) appears as a sine wave while b(t) appears as a cosine wave | ||
d. s(t) appears as a cosine wave while b(t) appears as a sine wave |
2.
What are the differences between the two plots a(t) and b(t)
a. a(t) and b(t) have the same amplitudes | ||
b. a(t) has a higher frequency than b(t) | ||
c. a(t) and b(t) appear as identical plots | ||
d. For every single cycle for a(t), two cycles of b(t) are seen |
3.
Select the correct observation for a(t) and b(t)
a. plots are same in amplitude | ||||||||||||||||||||||||||
b. plots are same in frequency | ||||||||||||||||||||||||||
c. since a(t) and b(t) phase angles are 0, a(t) appears as a sinewave that lags b(t), which is a cosine wave | ||||||||||||||||||||||||||
d. both b and c are correct
4. Having changed the message amplitude to Am=50, select the correct statement
