Noise Figures of Radio Receivers
Proceedings of the IRE, 1944A rigorous definition of the noise figure of radio receivers is given in this paper. The definition is not limited to high-gain receivers, but can be applied to four-terminal networks in general. An analysis is made of the relationship between the noise figure of the receiver as a whole and the noise figures of its components.

Amplifier noise figure optimization
Proceedings of the IEEE, 1968In the presence of lossy input filters, device noise figure data do not permit complete minimization of the amplifier noise figure F A . However, with L-filters such optimum can be obtained by a simple graphical construction on device noise figure records.

The noise figure of an optical transistor
Solid-State Electronics, 1968Abstract The equations for the effective noise current generators appearing across the terminals of an optical transistor with a constantly doped n+-p emitter junction are shown to be identical with those for a bipolar transistor. The noise figure of a Ga-As optical transistor of this type with the emitter dimensions of a good u.h.f.

Noise and noise figure in microwave receivers
2013The investigation of noise and noise figure in microwave receivers was commenced in the fall of 1948 at the U. S. Naval Postgraduate School and was continued through the winter in the electronics laboratory of the Glenn L. Martin Company at Middle River, Maryland. This field work was done to give the writer experience in the measurement of noise figure
