Figure 5. Schematic of Nyquist's 1928 thought experiment [6] [2] using two noisy resistors (each represented here by a noise-free resistor in series with a noise voltage source) connected via a long lossless transmission line of length . Each resistor's noise signal propagates across the line at velocity .
