If voice was to be transmitted at its basic frequency 20-20kc. it will take much time. But by transmitting a very hi frequency media the signal can be there presently. By modulating this frequency by voice and removing the media it can be there instantly.

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
In which Analog to analog modulation methods does the peak amplitude?
Frequency modulation Phase modulation
Why frequency modulation and phase modulation are called angle modulation?
i dont know ans. of this.
How does quadrature amplitude modulation works?
QAM is a combination of phase modulation & amplitude modulation.
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.
What is gfsk modulation?
whatbis GMSK MODULATION ?
