Lab Implement How to convert Y to F ?
Lab Inspect equations and we can find that Draw K-map to reduce F! F has sum of 9 products Y has sum of 8 products Draw K-map to reduce F! If we reduce F to less or equal than 8 SOP, then we can use Y to represent F
Lab Example Reduce And we can get
Lab Reduce again And we can get
Lab Please use other reduce method to do this lab LS 74151
