The incandescent element of an electric lamp is made of semiconductor material doped with donor or acceptor impurities having a concentration in the range 1017 to 1020 atoms per c.c. and providing energy levels not deeper than 05 ev from the conduction or valence bands. This concentration is ...
The principle of amplitude limitation is illustrated by the diagram of Fig. 2, which shows the saturation characteristic of an electron tube. The working point P of the tube is so adjusted on principle that the peak values of the disturbances having an amplitude which exceeds a predetermined lim...
