I am new to electronics and I am currently trying to learn a little more about how NPN and PNP transistors work. While doing some research, I stumbled across a circuit design called the Transformer-Less Push-Pull circuit. The schematic that describe such configuration is shown below:
My problem is that I am trying to understand and reproduce the circuit above but I am just not being successful.
So my question is: Do the schematics shown above represent a real circuit (something that can be physically built and can work successfully) or is it just a sort of circuit analogy?
If the circuit diagram show avobe is not a real buildable working circuit, could someone please point me to some schematics that represents a real buildable Transformer-Less Push-Pull circuit? If at all possible, something simple would be best as I am just a beginner and will most likely get lost if the circuit is not relatively simple.
