Amplitude Modulation is not only the approach of modulating the signal, but there also exist many other kinds of modulation techniques. Frequency Modulation is one of the types of modulation. In the earlier days of communications, the necessary bandwidth for transmission of signals was not wide and even they do not hold the ability to reduce the interference signals. In such a scenario, frequency modulation was introduced but it was not much accurate compare with amplitude modulation. Then … [Read more...]
