Hi again,
I have another simple but strange problem with transistors. I have attached a schematic. I used pspice to create it, but it is actually built and I am discussing real results (not a simulation). It is an emitter follower and as it is shown it works exactly as it should. The 20V signal goes into the transistor and comes out (at probe V) shifted so that the bottom of the wave just sits near zero, thanks to the biasing resistors.
However, when I remove the biasing resistors, the full wave still comes out but centered around zero. I would think that the negative side of the wave would be clipped and I would only see the positive part of the wave on output.
Does anyone know why this is happening? Is it supposed to?
