ECE 620 Dr. R. ROOSTA H.W # 8 SOLUTIONS 1) The composite Karnaugh map for the next state and external outputs for the given state diagram is shown as follows : 2) The logic hazard free equations for the circuit are : Y = A . B SUM = A' . B + A . B' = A + B CARRYOUT = y 3) Using the logic hazard free equations, we obtain the following gate level circuit.

Unformatted text preview: 5)Using the composite Karnaugh map for the S and R excitation inputs, we can write the following S and R excitation input equations and draw the circuit as shown below: The gate level circuit is somewhat simpler than the version of the circuit using S-R NOR latch. 6) Complementing the equations for the S-R NOR latch and using these equations, we can draw the circuit using S-R NAND latch as shown below: S' = A . B R' = A' + B'...
