In the shown diode logic circuit, A and B are inputs and C is the output. Which logic gate does the circuit represent? Image

G1 Physics · Accepted Answer

For positive-logic diode logic, the output becomes high when either input drives the output node high through a conducting diode. Thus the circuit performs OR. Correct answer: C.
