full_question: Fellgett’s advantage refers to the reduction of this phenomenon when multiplexing. The root-mean-square current generated by one type of this phenomenon is equal to the square root of 2 times current times the fundamental charge times the bandwidth. One form of this phenomenon was shown to correspond with the dissipation of electrical energy by resistance by Harry Nyquist. Boxcar averaging can be done to reduce this phenomenon A form of this phenomenon that occurs due to thermal motion is named for John Johnson. When this phenomenon has a constant power spectral density, it is called white. When taking measurements using electronics, it is important to minimize this phenomenon’s ratio with the desired measurement. For 10 points, name this phenomenon which consists of fluctuations that interfere with signals.
