Transponder – advanced satellite communication system

What is Satellite communication? Give Detailed explanation with diagram and mathematical analysis

The geosynchronous satellite orbits around the earth at a distance of about 36000km and it takes exactly 24 hours to complete its one revolution around earth. So it appears stationary at the location, from where it is launched.

What is Frequency Modulation

What is Frequency Modulation? Explain the process with diagram and mathematical analysis

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.

What is the Frequency Spectrum of Communication Systems? Why Modulation is necessary in wireless transmission?

What is the Frequency Spectrum of Communication Systems? Why Modulation is necessary in wireless transmission?

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.

What are the elements of communication systems? Explain with classifications of communication systems

What are the elements of communication systems? Explain with classifications of communication systems

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.
