Frequency modulation is defined as the process, in which the frequency of carrier signal is changed in accordance with the amplitude of modulating signal. To produce FM wave, a carrier signal of frequency fc is mixed with another low frequency modulating signal of frequency fm in a circuit known as frequency modulator.

We shall discuss in this article about the Frequency Spectrum of Communication Systems? Why Modulation is necessary. When signal is transmitted over an antenna, it is first converted into equivalent electromagnetic waves and after that the electromagnetic waves detach from antenna and travel into free space.

n this first part of the series we shall discuss about the fundamentals of communication systems. To exchange the useful information; like ideas, messages, an important document through a medium is called communication. The long distance electronics communication system started with the invention of telephone, by Alexander Graham Bell (1876). After that the communication systems developed very fast.
