8. 1. Explain how to add an asynchronous input to a Moore machine.
9. When designing a counter, the decision to make it an asynchronous or synchronous can depend on the frequency max. How is the frequency max different between asynchronous and synchronous? Explain your rationale.
10. 5. Using Quartus II, or an equivalent VHDL entry program, develop the text file and simulation for the 74LS194A universal, bi-directional shift register. Attach the .vhd and simulation files.
