Noise figures (linear transducers)
D.E. Meer · IEEE Transactions on Education · 1989
A short tutorial description of noise figures for two-port linear transducers and entire receiver systems is presented. Due to the long history and of the use of noise figures to specify noise performance, numerous definitions have evolved. The relationship between the various noise-figure definitions found in the literature are specified and tables are provided as cross reference to the notation and naming conventions used in the references.>
