8. (12 points) Using an 8 to 3 priority encoder (74148), realize a digital circuite 000,110 , and five switch selections according to the codes in the table of Figure 3. Codes OWO, The 74148 111 are not used. The inputs of the circuit are active high switches (SWI - SWS. The active low has eight active low inputs (ON to 7N ), one active low enable (EIN), and three active low outputs (A2N, A1N, gure 3. Coding Table
