In the course of designing FM systems, intermodulation noise is an important factor which deserves special attention.
The noise figure of a dual-pumped parametric amplifier with co-polarized pumps is quantified, for the first time to our knowledge.
The method of noise measurement is explained followed by an account of the effects on signal/noise ratio of load, operating point and output circuit.
The noise figure of a fiber-optical parametric amplifier, driven by pumps with orthogonal polarizations, is quantified experimentally.
ECHNICALLY correct results in a field are achieved initially in diverse and often confusing and complicated ways.
We have carried out an investigation of 40 years of solar radio burst data in a wide range of frequencies that have been reported by observing stations around the world during 1960-1969.

Forward Raman amplification using FBG-stabilized diodes yields higher signal RIN than expected from the Raman-gain-mediated transfer function.
The RF spectrum of an optical channel impaired by non-correlated incoherent amplified spontaneous emission is shown to be the sum of the RF spectrum of the two sources and the RF spectrum of the AS
