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

What is the relation between carrier frequency and modulating signal?

If the modulating system is AM (Amplitude Modulation) then the amplitude of the carrier wave changes with the amplitude of the modulation. On a specrum analyser that shows up as frequency sidebands. If the frequency of the carrier waves depends on the amplitude of the modulating signal that is called FM (frequency modulation). On a spectrum analyser that shows up as sidebands also.


What is effect of noise on digital communication system?

it will affect the output of a receiver only if it falls within the passband.in that case,the carrier and noise voltage will mix and the difference frequency,if audible,will interfere with the reception of the wanted signal..

What is spot frequency?

Spot frequency refers to the specific frequency at which a signal is transmitted, received, or monitored at a particular moment in time. It is the operating frequency of a communication system or device at a given instant.
