QUESTION 5Select the correct statement(s) regarding amplitude modulation (AM).

		a. If the AM Index is greater than 1 (i.e., AM>1), then over modulation occurs leading to signal distortion
		b. With AM, the message is captured as amplitude changes to the carriers amplitude.
		c. The AM modulated signal bandwidth is dependent upon the highest frequency (fm), and frequency bandwidth, of the message
		d. All of the above are correct

QUESTION 6

1. Amplitude Modulation (AM) describes a method where the baseband message is represented by carriers frequency.

True

False

QUESTION 8

1. Given the following parameters, select the correct equation for the modulated carrier signal. A_m=3v, A_c=3v, f_m=5500Hz, f_c=100MHz, _m=0, _c=0

		a. s(t) = 3[1+1.08 cos(25500t)] cos(2100E6t)
		b.s(t) = 3[1+1cos(25500t)] cos(2100E6t)
		c.s(t) = 3[1+6.5 cos(23500t)] cos(2100t)
		d. s(t) = 6.5[1+0.93 cos(2100t)] cos(2100E3t)
