Implicit in all these expressions is the belief that the technique is linear, or place yet another way, that
So the important first time period from the cascaded noise variable is minimized. Furthermore, an amplifier with
In power amplifiers the output tuning is commonly optimized for output electrical power and efficiency simultaneously. If a power amount above Psat is injected in to the amplifier, it will eventually work as an attenuator and show odd habits (if it is not ruined).

What do these nonlinearities appear like over the sign in the time domain? This depends on a lot of factors, together with simply how much bandwidth the amplifier supports. A great broadband amplifier will saturate by simply clipping off the ends of your output indicators, but this creates a quick transition that needs better get harmonics to generally be supported.
