Need for modulation

1) to reduce the antenna height

2) to multiplex the more number of signals

3) to reduce the noise & distortions

4) to narrow banding the signal

5) to reduce equipment

Need of modulation in communication?

Need for modulation: 1. Length of the antenna for a transmitter is inversly proportional to the frequency of the signal to be transmitted. So we try shift the frequency of the singal for the transmission to higher frequencies. 2. Every transmission of signal in a bandwidth is assigned with a particular frequency which is attained by modulating the signal with the carrier frequency. Different modulation techniques are implemented according to the requirements and compatibilities
