Abstract
In the first of this thesis the nature of random noise, which arise and theoretically cannot be eliminated from radio receivers, is described.
Nyquist equation, pertaining to the amount of noise generated in a resistor, is rederived by a simple method. The original equation as derived by Nyquist, is found to be valid, only, for physically realizable impedances of the minimum reactance type.
The general problem of a passive electric network excited by random sources is treated; a useful principle is developed for its solution.
Part II treats of the definition of the noise figure of a four terminal network and the most important methods available for its measurement. An improved noise generator for the measurement of noise figure is described.
