1) Discuss two methods to implement a simple 2 to 4 decoder. Why would one be better than the other?
2) Discuss the sequential nature of the Ripple Carry Output Adder. Why is it actually a sequential operation? What are problems associated with this type of sequential design? How would you alleviate them?
3) Suppose you had to control two seven segment displays using the same 4 bits of data lines, but each display had a separate enable, how would you decode a signal to control one then the other?
