Is modulated voice signal a baseband or broadband?

Neither.baseband refers to the original voice signal itselfbroadband refers to a form of wide bandwidth data transmission (e.g. internet traffic)the modulated voice signal consists of a carrier frequency and two sidebands, the bandwidth of the sidebands varies depending on the form of modulation used as well as the bandwidth of the original baseband signal, to reduce transmission power it is possible to eliminate the carrier frequency and to reduce overall bandwidth one of the sidebands may be partially suppressed or eliminated completely (but one sideband must always be fully retained)


How many sidebands does an FM signal generate?

2, 4, 6, 8, 10 it depends on the amount of modulation. 100%1 on each side, 200% 2 sidebands on each side.


What are the Applications of double side suppressed carrier modulation?

Each of the two sidebands can be modulated independently to give two simultaneous communication channels. There would be no point in radiating the carrier, as it carries no information, and would waste transmitter power.


What is one disadvantage of an amplitude modulation communication system?

One disadvantage of the standard amplitude modulation system is that 67% of the power is used for the carrier, but the carrier transmits no information, so it can be considered as wasted power.The 34% remaining power is split between two mirror opposite sidebands so, in effect, you really only have 17% of your power used to carry the signal.


What is the difference between am and dsb-sc?

In normal a.m. the sum of the power in the two sidebands can't exceed half the power of the carrier. For example, a 100W carrier when 100% modulated will have 25W in each sideband. Since both sidebands have identical information, one of them can be considered redundant. So we are transmitting 150W and making use of only 25W. In suppressed carrier d.s.b. we can achieve better efficiency since, with high suppression, we have 50% of the total power in each sideband. So a 150W transmitter, at 100% modulation, will radiate 75W in each sideband.
