  • Abstract
    A theorem is formulated and proved which determines the greatest lower bound of the single-frequency noise figure of a general system consisting of n amplifying devices and passive coupling elements. According to the theorem, this lower bound is equal to the noise figure of an optimum system using a selected one of these amplifying devices.
