This circuit takes an audio or sinusoidal signal and amplifies it. If the output is taken from the collector, then it is inverted, but if it is taken from the emiitter, then it is the same phase as the input sinusoidal signal and of greater amplitude than when taken from the collector.

The current in Rc and Re are almost equal. If the resistance of Rc is 4.7 times higher then the Re one, it must have an 4.7 in factor higher voltage at the collector, right!?

@ReneTheGreat You are having a little bit of confusion in you're description. If you measure the voltage at the emitter, it will be the same as the input just offset. In you're circuit you clicked on the resistor, which means you are measuring the current through it. Careful, the red and the green measurements can not be compared like that.

ViolationMad, you are right, i see you point now.
