Line Systems
Published in Dave Swallow, Live Audio, 2012
The advantage of all of this is that we can send a good, strong, clean signal down even a long balanced line cable without picking up hum; the high-frequency response of the signal is only limited by the capacitance of the cable. The distance along which you can get a clear signal is usually about 0.2 mile, which is almost certainly longer than the distance to the stage you’ll be mixing on.

A transmission line consisting of two conductors plus a braided shield, capable of being operated so that the voltages of the two conductors are equal in magnitude (voltage) and opposite in polarity with respect to ground. A balanced line offers common mode rejection or cancellation by attenuation; signals are electromagnetically induced into the signal lines.

A balanced line is a confi guration where the two wires are electrically identical. The electrical performance is referred to ground, the zero point in circuit design. Balanced lines reject noise, from low frequencies, such as 50/60 Hz power line noise, up to radio frequency signals in the Megahertz, or even higher.

Figure 3(a) illustrates the Phasor diagram of Generalized phase voltage, line voltage, negative sequence and positive sequence voltage. Figure 3(b) illustrates the polar form of symmetrical components which simplifies the calculation of sequence voltages and unbalanced factors. Positive and Negative Sequence Component are converted into Radial Component and Angular Component. Radial Component is the tangential component of sequence voltages. The magnitude of the radial component is equal to the overall RMS of Line voltages. This voltage is referred to as “Line Aggregate Root Mean Square Voltage” and abbreviated as LARMS voltage (Vλ). Total power delivered by unbalanced line voltages are equal to the power delivered by equivalent balanced line voltages with the value equal to this LARMS Voltage. This voltage magnitude is also estimated with phase voltages and zero sequence voltages. Magnitude of the zero sequence component is directly estimated with phase voltage magnitudes and line voltage magnitudes using Equation (26). Angular Component is equal to the arc tangent of the voltage unbalance factor which is the ratio between negative and positive sequence components. So this component is referred as “Tangent Angle of Unbalance (TAU)”. This angle is used for performance analysis of unbalanced systems.

Figure 6(b) shows that the amount of WIP in the system increases as the vehicle capacity increases, both for the balanced line and the unbalanced line. For a fixed vehicle capacity, the unbalanced lines have a higher WIP level, because the insufficient transporting rate of the vehicle leads to the accumulation of jobs in the buffers. Figure 6(c) indicates the changes in the probability of vehicle status, both for the unbalanced line and the balanced line. Both the probabilities of a vehicle being in pick-up idling and drop-off idling increase as the system tends to be balanced. No matter the line is balanced or not, the systems with larger vehicle capacity have a higher probability of the vehicle being in pick-up idling, while a lower probability of the vehicle being in drop-off idling. Figure 6(d) indicates the changes in the probability of batch size, both for the unbalanced line and the balanced line. For the unbalanced line, the probability that batch size equals to the vehicle capacity is the maximum. While for the balanced line, the probability that the batch size equals 1 is the maximum.
Miniaturized Vivaldi Tapered Slot Antenna (VTSA) with Microstrip to SIW Feed Structure for X Band Application

The radiating portion of the antenna, which is the tapering section, is a balanced line, but the feed portion, which is the microstrip line or coaxial cable, is an unbalanced line. To match the balanced and unbalanced components of an antenna, which serves as a Balun, a good transition section is required. The transition part must have some qualities such as compact, small, low loss, and easy to fabricate. But it is difficult to design a very wideband transition in practice because it limits the antenna performance at a higher frequency.
