Draw a 4-input XOR gate-level schematic using EXACTLY 15 two-input NOR gates and NO other gate types. Use three cascaded XOR2 modules, five NOR2 gates per module. Only external inputs: A, B, C, D. No complemented inputs. No XOR, XNOR, NOT, NAND, AND, or OR symbols. Use exactly these connections: Stage 1: XOR2(A,B) N1 = NOR(A,B) N2 = NOR(A,N1) N3 = NOR(B,N1) N4 = NOR(N2,N3) X1 = NOR(N4,N4) Stage 2: XOR2(X1,C) N6 = NOR(X1,C) N7 = NOR(X1,N6) N8 = NOR(C,N6) N9 = NOR(N7,N8) X2 = NOR(N9,N9) Stage 3: XOR2(X2,D) N11 = NOR(X2,D) N12 = NOR(X2,N11) N13 = NOR(D,N11) N14 = NOR(N12,N13) Y = NOR(N14,N14) Draw every NOR2 gate individually with complete wires. For NOR(N4,N4), NOR(N9,N9), and NOR(N14,N14), connect both NOR inputs to the same signal. Arrange three modules left to right. Label X1, X2, and Y clearly. Final result: Y = A XOR B XOR C XOR D Total: EXACTLY 15 NOR2 gates. Do not simplify the circuit or replace gates.
