7. (has three related parts) This problem asks you to implement a chip with four inputs (A = in[0], B= in[1], C = in[2], D= in [3]) that produces this Karnaugh map: CD 00 01 11 10 00 11 111 1 101 1 AB 01 a. [3 points) Write down the simplest boolean expression you can for the l's in the Karnaugh map (full credit for having just two terms): b. [3 points) Draw a sketch here (or on separate paper if you need more space) of your for the chip (if you can't correctly implement the code, you can still get some credit for the hand-drawn design)
