impedance-matching network

impedance-matching network

[im′pēd·əns ¦mach·iŋ ‚net‚wərk]
(electricity)
A network of two or more resistors, coils, or capacitors used to couple two circuits in such a manner that the impedance of each circuit will be equal to the impedance into which it locks. Also known as line-building-out network.
