1. Consider the 4-bit ripple adder shown below. Each NOT, AND and OR gate has a propagation delay of 1 tp, and an XOR gate has a propagation delay of 3 tp. Suppose the circuit is implemented just as drawn, i.e., don't replace the XOR gates with AND-OR combinations. What is the worst-case delay from any input (A, B or Cin) to the final carry output, C4?
