What is the phantom circuit?
The phantom circuit can be created when electrical wires for one circuit are also configured to perform signals for others. It is often used for telephone systems and electrical engineering, as well as power recording and microphone broadcasting. Fantom circuits are usually dependent on the operation of an audio transformer called a repetitive coil, which often includes different wire lengths around iron, nickel or other type of core. These coils are usually part of a simplex circuit, which usually consists of cables connected to the main electrical line and the connection of the telephone device. Two simplex circuits can be combined to form a third; This other circuit is also called a phantom group.
When one winding in a repeated coil, also called the center transformer, is exposed to the AC current (AC), the other wire usually has an equally strong signal. Connecting telephone lines with repeated coils is therefore suitable because voice and signals are usually poweredAC. Repeated coils are located on both sides of the phantom circuit, while the connection between the wires can be made at the ends or in the middle of the perimeters. The current applied in the center is usually divided evenly between each wire if the electrical resistance of each is the same.
Two currents on the same line usually travel in different directions and can cancel each other. Telephone signals that are connected to the Simplex electrical circuit are also usually not to the end points of the other lines. Other features such as Morse Code, without a degradation telephone function can be added to the phantom circuit, especially when the country is used as a conductor. Frequent maintenance of these circuits is usually important because electrical interference in lines can cause unintelligible voice signals.
If more RK creation more connections are used by EPEAT coils, more phantom circuits can be created. This technology was the first timeé used at the beginning of the 20th century. Telephone companies often tried to maximize how many circuits could be on long lines without having to create additional equipment.
Phantom Circuit can also be used on direct current signals (DC) in telecommunications, while more modern carrier telephone systems often also use them. Configuration of Phantom circuit normally allows telephone companies to get a cable power plant that can handle the largest operation. This potentially saves income, because operators often need fewer equipment and can add more subscribers to each line.
