1. Find the simplest POS expression using a K-Map for the function f(x1, x2, x3, x4) = IIM (1, 3, 4, 6, 7, 9, 13, 14, 15) List all prime implicants found in the K-Map, list only the essential prime implicants, and write the simplest expression. 2. For the expression f (x1, x2, x3, x4) = IIM (3, 5, 7, 12, 13, 14) + D (0, 4, 11, 15): i. Does it make more sense to use SOP or POS to solve this? Explain your reasoning. ii. Determine the simplest SOP solution. Clearly identify what value you are using for the don't cares and show work. iii. Determine the simplest POS solution. Clearly identify what value you are using for the don't cares and show work. Submit your answers online. If you wrote your answers on paper and don't have access to a document scanner, Adobe Scan from Google Play and the Apple Store is one option (there are many other scanning apps that use your phone - feel free to suggest others on the Slack channel that you've found useful). You can use this to create a single PDF document of your work and then submit to Canvas.
