Magnetic amplifiers (history) — The magnetic amplifier (sometimes called a self saturated amplifier ) is a magnetic device consisting of a saturable reactor (transformer) modulated by a direct current. This DC current is introduced in the primary winding of an iron core… … Wikipedia
Impedance matching — In electronics, impedance matching is the practice of designing the input impedance of an electrical load (or the output impedance of its corresponding signal source) to maximize the power transfer and/or minimize reflections from the load.… … Wikipedia
