Alexander Graham Bell discovered that which type of cabling cancels out electrical interference?
Twisted pair Twisted pair Twisted pair cabling is a type of wiring in which two conductors of a single circuit are twisted together for the purposes of improving electromagnetic compatibility. Compared to a single conductor or an untwisted balanced pair, a twisted pair reduces electromagnetic radiation from the pair and crosstalk between neighboring pairs and improves rejection of external electromagnetic interference. It was invented by Alexander Graham Bell. In a balanced line, the two wires carry equal and opposite signals, and the destination detects the difference between the two. This is known as differential signaling. Noise sources introduce signals into the wires
IEEE Alexander Graham Bell Medal IEEE Alexander Graham Bell Medal The IEEE Alexander Graham Bell Medal is an award honoring ""exceptional contributions to the advancement of communications sciences and engineering"" in the field of telecommunications. The medal is one of the highest honor awarded by the Institute of Electrical and Electronic Engineers for achievements in telecommunication sciences and engineering. It was instituted in 1976 by the directors of the world's largest professional society, the Institute of Electrical and Electronic Engineers (IEEE), commemorating the centennial of the invention of the telephone by Alexander Graham Bell. The award is presented either to an individual, or to a
