Biography
He received a master's degree in electrical engineering from the University of Delft in 1923, he got a job at the Philips Physical Laboratory (Philips Natuurkundig Laboratorium) in Eindhoven. In 1926, he invented the pentode vacuum tube, and already in 1948, the gyrator. The gyrator can be used to create sections of the circuit that simulate inductance without resorting to coils. For example, you can use a gyrator in graphic hi-fi equalizers. In total, Tellegen owns 41 patents.
In the period from 1946-1966. Tellegen taught electrical circuit theory as an associate professor at Delft University of Technology. From 1942 to 1952 he was president and honorary member of the Netherlands Society for Electrical and Radio Engineering.
The Australian Institute of Radio Engineering awarded Tellegen the title of lifetime honorary member in 1953. Tellegen was also a member of the Institute of Electrical and Electronics Engineers and in 1973 received the Edison Medal "For a significant contribution to the development of the theory of electrical circuits, as well as for the invention of the gyrator." In 1960, Tellegen became a member of the Royal Netherlands Academy of Sciences . In 1970, the University of Delft awarded Tellegen a doctorate for his services in the field of electrical engineering.
