= Impedance matching
{wiki=Impedance_matching}
Impedance matching is a technique used in electrical engineering and telecommunications to ensure that the impedance of a load (such as an antenna or a speaker) matches the impedance of the source (such as an amplifier or a transmission line). The main goal of impedance matching is to maximize the power transfer from the source to the load and to minimize signal reflection, which can degrade the performance of a circuit or system.
