## balanced circuit

[′bal·ənst ′sər·kət]
(electricity)
A circuit whose two sides are electrically alike and symmetrical with respect to a common reference point, usually ground.
An electric circuit that has been adjusted to neutralize the mutual induction of an adjacent circuit.

## Balanced Circuit

an electrical circuit whose action is based on the geometric equilibrium (balance) of the currents (voltages) in it, or on the upsetting of that equilibrium when changes occur in a circuit parameter or in the frequency of the supply current (or supply voltage). Balanced circuits are used as electrical bridges for electrical and electronic measurements, as transducers converting one form of energy to another, and as modulators and detectors in devices of single-band radio communications, high-frequency telephone communications, and so on.

## balanced circuit

A three-wire electric circuit in which the load is the same on each side of the neutral wire.

The balanced circuit has attracted much attention for its higher immunity to environmental noise than the unbalanced circuits.
The frequency, phase (120[degrees] apart), and amplitude of the input power are balanced so their sum at any point in time is equal to zero, thereby providing a balanced circuit.
If the heated wire is made to be one leg of a Wheatstone bridge with a balancing leg exposed to ambient temperature as a compensator, and both of these are set against two fixed resistors, a balanced circuit will go out of balance as the sensor wire changes resistance with pressure changes that modify the wire's temperature.
A software balun enables a balanced circuit to be replaced with unbalanced parameters.
Good isolation was also observed for the balanced ports, indicating that the proposed hybrid can meet the required performance of the balanced circuit.
It is a balanced circuit containing two identical and symmetric sub-circuits.
The balanced circuit also doubles the limiter's power handling capability.
Like the balanced circuits they require the circuit to bring the selected state.
Here are models for circuits that provides details on noise figure, consider the effects of balanced circuits on gain, and provide supporting insights on electromagnetic concepts as they relate to overall circuit theory.
The most important advantage of balanced circuits with differential-mode operation is higher immunity to environmental noise compared to unbalanced circuits with single-ended signaling [1-3].
