Johnson–Nyquist noisen.

Brit.

/ˌdʒɒnsnˈnʌɪkwɪs(t) nɔɪz/, U.S.

/ˌdʒɑns(ə)nˈnaɪˌkwɪs(t) ˌnɔɪz/

Origin: From proper names, combined with an English element. Etymons: proper names Johnson , Nyquist , noise n.

Etymology: < the names of John Bertrand Johnson (1887–1970; born Johan Erik Bertrand), Swedish-born U.S. physicist, who published an account of it (see Johnson noise n.) + Harry Nyquist (1889–1976), Swedish-born U.S. engineer, who first explained the phenomenon + noise n.

Electronics.

Electrical noise caused in a circuit by the thermal agitation, and subsequent random motion, of the charge carriers in a conductor.
