Can the emitter and collector of the common-emitter amplifier circuit be connected to the capacitor output?

First of all, the emitter and collector of this common-emitter amplifier circuit can be connected to the capacitor output, and it can be measured that both the E and C poles have signal output, where the collector signal output size is equal to the resistance Rb1 and Rb2 that determine the base bias voltage. The ratio is multiplied by the size of the input signal, and the phase is reversed. The size and phase of the signal taken from the emitter are equal to the original signal. The triode only has such characteristics, and it does not depend on what circuit is in. This is its law. The signal taken out by the collector can be amplified in reverse phase (the amplification factor or the specific analysis of the specific circuit), and the emitter is equal in size and phase. .

These two capacitors should remove the DC component of the signal. It seems that there are such capacitors in the audio amplifier circuit.

Both can be output, the emitter is the same size as the input, and the collector and emitter are the same size.

The role of this circuit:

Convert one AC input signal into two AC output signals with equal amplitude and opposite phases.
