Modulation in radio broadcasting is important because it is necessary to adjust the carrier signal so that the information in the modulating signal can be broadcasted. You must have modulation in order to transmit thru a radio wave.

Why the carrier for the amplitude modulation must be a sinusoidal waveform?
The wave in amplitude modulation must be a sine wave. A sine wave represents smooth repetitive oscillation, which is necessary for this process.
Why is modulation necessary before multiplexing?
modulation means transmitting the signal which is to be transmitted along with the carrier wave, then at the receiver it is separated from the carrier and demodulated. So modulation is needed so as to transmit the signal over long distances with higher accuracy. Hence it is required before multiplexing.
How velocity modulation and density modulation related to each other?
due to velocity modulation density modulation occurs in TWT
What is the unit for modulation index?
Modulation index is also called as Modulation depth. The modulation index of a modulation scheme describes by how much the modulated variable of the carrier signal varies around its unmodulated level.
Advantages of hybrid modulation over digital modulation?
presentation of analog digital hybrid modulation
How do you xxplain Why modulation is desirable?
Explain why modulation is necessary or desirable.
Why modulation is necessary?
modulation is necessary for transmitting low frequency signal to long range with desired qualitative information
What is necessary in order to interpret a signal?
Operating system

Why is modulation necessary in signaling?
If you didn't have modulation it'd be the same signal going out the whole time, like a continuous tone - which can't really tell you that much. By modulating the signal you can say much more.
Why normalization of message signal is necessary in conventional amplitude modulation?
to maintain the constant frequency and the phase parameters at the output
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
