Consider the circuit shown. The circuit of the Experiment 1 is readily changed to obtain a proper common emitter circuit...
![]() Common emitter circuit. (Enlarge) |
![]() Circuit diagram of a common emitter circuit. |
The circuit is designed so that when pressing the push-button switch S1 of the transistor is saturated and completely switches through...
This is the opposite outcome of the first experiment, a proper common emitter circuit inverts the input signal!
A common emitter circuit is inverting |
But what about the gain of the current in a common emitter circuit...?
