  • Remote Sensing

    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,…

  • Earth’s Satellites

    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…

  • Difference Between Am and Fm

    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…

  • Special Theory of Relativity

    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…

  • Satellite Communication Active and Passive Satellite

    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…

  • Pulse Amplitude Modulation

    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…

  • Energy Orbiting Satellite

    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…

  • Types of Lever

    Introduction In order to lift or move any material, the lever is used. Sometimes the lever helps to push against materials but does not move them actually. It generally works in order to decrease a certain amount of effort force that is necessary to move loads. All lever provides mechanical advantages but a longer one…

  • Bridge Rectifier – Construction, Working, Advantages

    Introduction Bridge Rectifier convers AC input into DC output. The rectification process is done by the junction diodes which are forward biased. When a junction diode is forward biased, it admits the current to flow through it. This application of junction diodes is mainly used in rectification. The Wheatstone Bridge system is used in Bridge rectifiers. Bridge rectifiers are also called Wave…

  • Types of Circuits

    Introduction Energy is supplied to a circuit with a generator or a battery. In a circuit, energy is converted from different forms such as electromagnetic, chemical, thermal, and mechanical forms into electrical forms. An electrical charge is used to carry energy to the electrical circuit. Energy enters a circuit with the help of one or…
