Volts/root Hz
[edit]I modified the previous rationale which stated that V/root(Hz) "is derived from the fact that doubling the bandwidth...," which seems to be faulty logic. V/root(Hz) is a way of describing the standard deviation of the signal, when the power of the signal is known. Also, doubling the bandwidth will not double the power when the signal does not have a flat spectral density.
