Modulation is, generically, a means of shifting information from one frequency domain into (typically) a higher frequency domain. This provides a number of benefits; among them: Two or more input signals with matching or overlapping frequency domains may have their information shifted into disjoint frequency domains; if such signals travel together through a medium, having their frequency domains be disjoint will allow them to be separated. In many cases it's easier to uniformly handle signals where the minimum frequency is a substantial fraction of the maximum, than signals where the maximum is many times the minimum. An audio signal whose frequency content is 20-20,000Hz has a 1,000:1 spread between the minimum and maximum frequencies. If such a signal were amplitude-modulated at 1MHz, the spread would be about 4% [from 980,000Hz to 1,020,000Hz]. Even if there were no other radio communications anywhere in the world, trying to design an antenna which could work well with a 1,000:1 frequency spread (from 20Hz to 20KHz) would be very difficult. Designing an antenna to deal with a 4% spread would be much easier. Some use cases for modulation exploit both benefits; others only rely upon one or the other. read less

For adding the strength to the message signals and to transmit them longer distances we add high-frequency signals. This process of adding signals is called modulation.

The message signals will be of low frequency and hence cannot travel longer distances. For adding the strength to the message signals and to transmit them longer distances we add high-frequency signals. This process of adding signals is called modulation. Modulation increases the signal strength and makes the message signal immune to noise and hence, can transmit longer distances. We can compare this with a simple example in our daily life. When we speak the voice can travel only smaller distances, but when we use a microphone and loud speaker, the same voice is amplified and transmitted longer distances. read less

message signal which are supposed to carry information will be of lower frequency,this implies that these message signals are not strong enough to reach the satellite which are far away from earth surface. To make this transport of message signal to satellite then back to the receiver we superimpose the message signal over a high frequency signal which can cover the required distance ,such high frequency signals are called as carrier signal,this process of super impose is called Modulation read less
