-- The power output stage in the transmitter must be operated either class A or
class B. Whereas in FM the power output stage in the transmitter can operate class C
which uses much less power per watt delivered to the antenna.
-- For full modulation, audio power is required equal to 1/2 of the RF power of the
transmitter output stage.
-- At full modulation, 2/3 of the total power arriving at the receiver is at the carrier
frequency, which conveys none of the information.
-- A receiver designed for AM reception is susceptible to a wide variety of natural
and man-made noise.

Which cellular system uses the most bandwidth efficient modulation?
I think it is Frequency Modulation with Phase modulation which it the most bandwidth efficient
What are the advantages frequency modulation amplitude modulation?
Frequency modulation have some advantages over amplitude modulation, FM is not sensitive to the amplitude noise, and have high efficient use of transmitted power
Why modualtion is need?
Without modulation, there's be no way to get any information onto a carrier signal. There are several different types of modulation schemes for radio carriers and almost as many different types demodulators to decode the information so that it can be converted into a usable form. For instance, AM (amplitude modulation), FM (frequency modulation), digital modulation, quadrature amplitude, etc.
What are examples of analogies?
It is a way to see differentences between items. Like: Cow is to barn as elephant is to zoo.
What does AM and FM stand for in radios?
AM - Amplitude Modulation FM - Frequency Modulation
Need for modulation?
modulation
What are the two types of angle modulation?
Frequency Modulation and Phase Modulation
When modulation frequency is double the modulation index is halF and the modulating voltage remains constant the modulation system is?
frequency modulation..
How velocity modulation and density modulation related to each other?
due to velocity modulation density modulation occurs in TWT
What is the difference between frequency modulation and phase modulation?
The difference between frequency modulation and phase modulation is that with frequency modulation the angular frequency of the signal is modified while with the phase modulation, the phase angle of the signal is modified.
When modulation frequency is doubled the modulation index is halved and the modulating voltage remains constant the modulation system is?
the modulation system is of FM
Why frequency modulation and phase modulation are called angle modulation?
i dont know ans. of this.
