Input voltage source

A standard independent input voltage source symbol for a circuit schematic, drawn in clean black line art as a simple circle with a thin outline, plus and minus polarity markings, and two straight connection terminals, typically one above and one below. The symbol may include a nearby input label such as vi, vin, Vid, Vs, or Vsig, and is intended as a reusable textbook-style signal source block.
