Description
• For this lab, only use the 74HC08, 74HC32, and 74HC04 ICs to implement your logic, the bar LEDs
as outputs, and the switches as inputs
• Find the minimal SOP expression of J and K using Karnaugh maps when you optimize the equations
separately
J (w, x, y, z) = Xm (1, 3, 9, 11, 12, 13, 14, 15)
K (w, x, y, z) = Xm (0, 1, 3, 12, 14)
• Calculate how many gates and total gate inputs are required to implement J and K when optimized
separately
• Calculate how many gates and total gate inputs are required to implement J and K when optimized
separately and when you can only use 2-input gates
• Jointly optimize J and K to use the minimum number of gates using Karnaugh maps
• Calculate how many gates and total gate inputs are required to implement J and K when jointly
optimized and when you can only use 2-input gates
• Implement your jointly optimized solution using ICs
– Verify your implementation yields the correct outputs using a truth table
– Demonstrate your implementation to your lab TA
