If both inputs of a 2-input NOR gate are tied together and driven by the same signal A, what single-function behavior does the device implement?

Introduction / Context:Gate reconfiguration through tying inputs is a classic technique for reducing parts and creating needed primitives. With NOR and NAND (universal gates), tying inputs can yield inversion, enabling construction of other logic functions.

Given Data / Assumptions:

• 2-input NOR gate with inputs connected together: A, A.
• Standard binary logic levels 0 and 1.
• No additional components assumed.

Concept / Approach:NOR is NOT(OR). With identical inputs, OR(A, A) equals A. Therefore, NOR(A, A) equals NOT(A). Thus, the tied-input NOR behaves exactly as an inverter. This property is exploited when building universal-gate-only designs: NOT, OR, and AND can all be composed using NOR gates.

Step-by-Step Solution:1) Start from the NOR definition: Y = NOT(A OR B).2) Tie inputs: B = A, so Y = NOT(A OR A) = NOT(A).3) Conclude that the gate acts as an inverter on signal A.

Verification / Alternative check:Truth table check: if A = 0, output = 1; if A = 1, output = 0, matching an inverter behavior exactly.

Why Other Options Are Wrong:“OR gate” is the opposite function before inversion. “AND gate” is unrelated to tying NOR inputs. “any of the above” cannot be true because only one behavior results from the identity OR(A, A) = A.

Common Pitfalls:Assuming tied inputs average or produce undefined levels; overlooking that OR with identical inputs reduces to the input itself, making NOR a straightforward inverter.

Final Answer:inverter
