7-11 A90-MHz carrier is to be frequency modulaled by a 2-kHz tone. The maximum frequency deviation is to be
Brief description :
Modulation technique is one of the major advantage which is exist in the communication system.
In present modern technology without modulation none of the communication is going to happen between sender and the receiver.
Because all the message signals or baseband signals are having low frequency components in them.
Because of having low frequency of message signals we cannot transmit these signals to longer distances.
If we wish to transmit these signals to longer distances, then there will be attenuation in the signal at the receiver.
For the faithful reception of the signal at the receiver we will use modulation.
In modulation we use high frequency carrier signals for the transmission of the low frequency message signals.
