Applications in communication systems

What is a cyclotron? A cyclotron is a mechanical device that was invented by the American nuclear scientist Ernest O. Lawrence in the year 1929-1930 to speed up a charged particle. The cyclotrons that were made early on were of small size, and later, different dimensions were designed based on the requirement. Early cyclotrons had […]

A galvanometer is an instrument for detecting or measuring a small electric current by movements of a magnetic needle or a coil in a magnetic field. A galvanometer is used to measure small electric currents in the nano-amp range and is used in applications such as electrometers, galvanometers, and ammeters. A moving coil galvanometer is

The component that is used to limit the passage of charge in most electronic circuits is commonly known as a resistor. Resistors are an important part of electric circuits. The term “resistance” refers to a measurement of charge flow restriction by the resistor. Most circuits use several resistors to govern the passage of charges in

Circuit switching and packet switching are two alternative switching techniques for connecting several communicating devices to one another. Circuit switching differs from packet switching in that packet switching is connectionless, while circuit switching is connection oriented.  Switching Switching is the process of sending data from one port to another that leads to the destination. If

Introduction Otis Boykin invented an improved version of the electrical resistor and got its patent in 1959. The resistor allowed a precise electric current to flow through a component. He made this invention in 1959. Two years later, he invented an even better resistor. This new resistor could be manufactured easily at a considerably low

Conductors are materials or substances that allow current to flow through them. Moreover, they can carry out electricity because they allow electrons to flow within them easily.  When an object gets the supply of an electric charge, it distributes across the object’s entire surface. Thus, it results in the object’s movement of electrons.  There are
