Mix two Signals with a Transistor ?
I would like to see if it is possible to mix two signals with one transistor: I don't have equipment to test it but would like to know at least theoretically what could I expect: I want to mix two signals and get some kind of mixed output, it doesn't matter how they are combined, just a random mix of the two signals.
So I though about injecting a signal into the Collector, a different signal into the Emitter and see what could come out of the Base terminal: I expect a very weak signal obviously since I am using the transistor not really as an amplifier but as some kind of mixing signal system, but the weak signal should be some kind of mix between the two signals injected into the Collector and Emitter, using the Base as an Output.
Would it work ? Could I expect to see some kind of mixing of the Signals ? Thanks for any advice or ideas...
I am not trying to solve any "problem", I am not trying to perform any "function", etc. I was just curious to know what happens if a signal is injected into the Collector and another in the Emitter and the base is used as an Output: I know that this is not "the way transistors are used", I know that you can mix signals in many other ways, etc (like injecting a signal in the Emitter and a different one in the Base and getting the Output from the Collector, etc. ), etc.
I was just wondering how a transistor would behave if you made it work "upside down" in a sense, just for "fun" and "curiosity".
I thing that you could expect a very weak signal out through the Base because of "leakage currents" and signals and such ?

Obviously not, because they are, and it is called a common base configuration and it finds special application.

Wrong Answer: tell me what could come out of the Base if it is used as the Output...
