Dwight O. North (September 28, 1909 - June 26, 1998)[1] was an American engineer and physicist. North worked for the Radio Corporation of America (RCA), first in Harrison, New Jersey, and later in Princeton.[2] He initially dealt with noise in vacuum tubes in the 100 MHz band as part of the development of television.[3] After World War II, he turned his attention to solid-state physics.[3]

North was the first to formalize the concept of the matched filter and is credited with its invention.[4] The term "matched filter" comes from a 1944 paper called "A Theoretical Comparison of the Visual, Aural, and Meter Reception of Pulsed Signals in the Presence of Noise" by David Middleton and his PhD advisor, John Hasbrouck Van Vleck, published in the Journal of Applied Physics.[5]

North received the 1961 David Sarnoff Outstanding Achievement Award in Science.[1] In 1998, he received the Golden Jubilee Award from the IEEE Information Theory Society.[6] North was buried at Trinity All Saints Cemetery in Princeton, New Jersey.[1]
