Q. 1.In the process of transmission of message/ information signal. noise gets added to the signal anywhere between the information source and the receiving end. Can you think of some sources of noise?
Q. 2.In the process of modulation, new frequencies called sidebands are generated on either side (higher and lower than the carrier frequency) of the carrier by an amount equal to the highest modulating frequency. Is it possible to retrieve the message by transmitting (a) only the side bands. (b) one side band?
Q. 3. In amplitude modulation, modulation index is used. What will happen if ?
Dear Student ,
1. Due to change in amplitude there is increase in noise in signal .If there is less change in amplitude then noise produced is less .
3. If then modulation index increases due to which modulation does not holds good .
Kindly ask different question in different posts .
Regards
