Abstract

Step amplifier that consists of two transistors arranged in collector series (1) with transmitter (2) for amplifying small or medium-sized signals, or, during a second operation, by a transistor device arranged in series, and in both operations in collaboration with conventional elements such as condensers, resistances, and a voltage supply.
