Introduction Electronic communication systems dissolve the communication power to both the positive and negative impacts. Analogue or digital signals are fed to the system, processed in the circuits electronically for transmission and then deduced by the receiver. Electronic communication systems are said to be highly reliable and efficient when the errors are minimised in the…

Introduction A satellite is a smaller object that is built for collecting information about the happenings in the space. Satellite communication on the other hand, is the process of sharing information between the satellite and the earth’s stations. This communication ensures that people on earth are being updated about the small to big happenings in…

Introduction Remote Sensing is one of the scientific methods that help to detect the physical properties of an area. This process is done without having any physical contact with the targeted objects. This process is mainly used for gathering information about different solar planets and Earth. Different types of fields like geology, ecology, meteorology, hydrology,…

Introduction A satellite is an object that revolves around a planet in a curved path. When it comes to satellites, there are two major types of classification. The first is a natural satellite, and the second is an artificial satellite. A natural satellite is one of the celestial bodies that orbit a larger body in…

Introduction Wave is the disturbance in the medium to transfer energy without the transfer of mass. Waves are usually in a periodic motion like a simple harmonic oscillator. They have crests and troughs. The amplitude of the wave is the height of the wave. The distance covered between two consecutive crests is called the wavelength…

Introduction Special theory of relativity is one of the most important theories in the field of physic. Special relativity describes the relationship between energy and mass. The theory further states that a small amount of mass can be transposable with a huge amount of energy. It is defined by the famous equation E=mc2E=mc2. The special relativity…

Introduction In order to shape telecommunication in the present day, satellites are considered one of the crucial parts of the entire communication system. The presence of artificial satellites helps in receiving a fast and easy transmission of both kinds of signals such as analogue and digital. Focusing on this particular parameter of telecommunication the parent…

Introduction The Pulse Amplitude Modulation is referred to as a very simple model of signal modulation technique. These are the signals that are further transmitted and are inspected at a very particular interval. On top of it, the modulating signal is proportional directly to the amplitude of the signal Therefore it general multiple carrier signals…

Introduction All the planets in the solar system are found at different distances. The first four planets are closer to each other and closer to the Sun. They form the inner solar system. The planets in the outer solar system are far away from the Sun. Remote censoring is the collection of information about objects…
