High-power RF amplifiers are used in telecommunications, biomedical, and military systems. With output power levels ranging up to 1 kW, these amplifiers are typically designed to operate near or into ...

AGC (automatic-gain-control) amplifiers use the nonlinear characteristics of control devices. The magnitude of the real component in some of their differential parameters changes depending on ...

A new femtosecond fibre laser design combines two distinct regimes of nonlinear dynamic attraction within a single cavity to yield robust and low-noise performance. Ultrafast science impacts nearly ...

As we’ve traced our no-nonsense path through the world of Hi-Fi audio, we’ve started with the listener, understood the limitations of the human ear, and thence proceeded to the loudspeaker. We’ve ...
