Introduction,l amplification. It has been found convenient to refer both the noise power and the signal power to the input of the amplifier, before amplification, because then one can make a direct comparison between the amplifier noise and the thermal noise that accompanies the signal. We have gone so far as to

Linear Noisy Multiports, waveguides. If signal distortion is avoided, these devices are characterized as linear multiports. Of course, even linear multiports may distort a broadband signal by introducing frequency-dependent changes of the amplitudes and phases of the Fourier components of the signal. A linear multiport wit

Quantum Theory of Waveguides and Resonators,f energy occurring in quanta. This led to the Bose—Einstein distribution of photons, a distribution of thermal equilibrium. Then we studied the noise of classical linear systems, and determined the optimum noise performance of a linear two-port amplifier with specified internal noise. In this chapte
