What is a balanced line?

The balanced line indicates a transfer line used in telecommunications and sound. This is also called a balanced pair of signals. Usually, balanced lines have three wires. These conductors consist of two signal conductors and ground wires.

In balanced parts, two signal wires carry the same signal. But they have the opposite polarity. These two wires also have the same impedance at each end.

The balanced line connection reduces noise and interference and is used in long cable transmission lines. Top sound devices, as well as some compact disc and amplifier players, use balanced lines with connections using three XLR connectors. Balanced lines can also be found in ethernet cables and telephone wires. First, two unbalanced telegraph lines were used. However, this was insufficient because the telephone wires often ran next to the electric wiring.

Thinky E closest to the electrical guidance would have greater interference than the second line. DealIt was to have two rows of swap positions at regular intervals to allow each other the same amount of interference. However, as more and more phones were used, the cable became preferred over open wires to save space and have better performance in bad weather.

The

balancing lines are used because noise and interference can cause problems when transferring the signal over the line. These problems are caused by electromagnetic interference from vicious electrical fields. In the balanced line, both wires are twisted together so that they can be evenly exposed to the outer electric field, minimizing this interference from vicious fields. In order to ensure even less interference, an electromagnetic shield will also be often balanced.

There are two types of balanced lines: twisted couple and twins. Estened lines of twisted pairs are used for lower frequencies while for frequency signalsSignals are used double lines. The balanced double line lines consist of two copper lines or copper steel lines that are separated by plastic polyethylene ribbon. They must be separated to function as parallel transmission lines.

Balanced cables of the twisted vapor have been designed, but were not used too much until the repetition amplifier was available. Previously, the cable could only work about 18 miles (about 30 km) length, while open wires could work at much longer distances. All distance problems were solved in 1912, when repetition amplifiers began to be installed.

Balanced lines are an alternative to an unbalanced line such as a coaxial cable. Unbalanced lines have their back conductors attached to the ground or backpoint, which is actually the ground. Both types of rows can be connected using a transformer called Balun.
