The design for a full-adder shown in the figure below is used in the implementation of an 8-bit ripple carry adder in a processor ALU. The gates used in the full adder implementation have different delays, as follows: • AND gate - 1ns • OR gate - 2ns • XOR gate - 4ns What delay is observed until the output signal stabilise in the 8-bit adder when the inputs change from a = 00000000, b = 00000000 and cin = 0 to a = 00000001, b = 00000001 and cin = 1? a 33ns 3ns 7ns 10ns cin- D cout The design for a full-adder shown in the figure below is used in the implementation of an 8-bit ripple carry adder in a processor ALU.
