The NOR gate<\/b> (NOT-OR) is a fundamental logic gate used in digital electronics. It gives a LOW (0)<\/b> output if any of its inputs are HIGH (1)<\/b>. If all inputs are LOW<\/b>, the output is HIGH<\/b>.<\/p>\n
Building a NOR gate using transistors helps you understand how logic gates function at the hardware level. The circuit works by using NPN transistors<\/b> to detect the presence of HIGH signals at the inputs. If either transistor receives a HIGH signal at its base, it conducts, pulling the output LOW.<\/p>\n
If\u00a0 both inputs are LOW<\/b>, neither transistor conducts, and the output is pulled HIGH through a pull-up resistor<\/b>.<\/p>\n
