The use of negative feedback reduces the gain. Part of the output signal is taken back to the input with a negative sign. ...

... The high speed of electrical signals results from the fact that the force between charges acts rapidly at a distance. Thus, when a free charge is forced into a wire, as in Figure 20.5, the incoming charge pushes other charges ahead of it, which in turn push on charges farther down the line. The dens ...
