Johnson noisen.

Brit.

/ˈdʒɒnsn nɔɪz/, U.S.

/ˈdʒɑns(ə)n ˌnɔɪz/

Origin: From a proper name, combined with an English element. Etymons: proper name Johnson , noise n.

Etymology: < the name of John Bertrand Johnson (1887–1970; born Johan Erik Bertrand), Swedish-born U.S. physicist, who published an account of it in 1928 (‘Thermal Agitation of Electricity in Conductors’, Phys. Rev. 32 97 ff.) + noise n.

Electronics.

Electrical noise caused in a circuit by the thermal agitation, and subsequent random motion, of the charge carriers in a conductor.Also called Johnson–Nyquist noise, Nyquist noise, or thermal noise.
