Baluns are commonly used in radio and audio applications to connect balanced transmission lines, such as twisted pair cables, to unbalanced systems, like coaxial cables. They help in matching impedance, reducing...") | |||

The two halves can then produce or be fed by two AC voltages equal in magnitude but opposite in phase. In a power supply this allows full wave rectification with 2 diodes instead of 4. In a Class B amplifier the two halves may be driven in opposite phase by two power transistors...") | ||||
