Generic transistor small signal equivalent

A compact schematic-style small-signal equivalent circuit for a transistor, with the device replaced entirely by linearized elements: an input resistance, a dependent current source or central gain element representing transconductance, and an output resistance. The diagram includes clearly labeled input and output terminals, a ground reference, and optional polarity marks or a load resistor at the output. Resistive elements may be labeled conceptually as rpi, ro, or re. Rendered as neat monochrome textbook line art using only standard circuit symbols and no physical transistor outline.
