01.) Show the truth table for a 4-input priority encoder in which S0 has the highest priority, S1 has a higher priority than S2, S3 has the lowest priority, and V is equal to 1 when all inputs (S0 - S3) are zero.
My guess ... ( I would prefer S3 to be on the left )
| S0 | S1 | S2 | S3 | V | A1 | A0 |
| 0 | 0 | 0 | 0 | 1 | x | x |
| 0 | 0 | 0 | 1 | 0 | 0 | 0 |
| 0 | 0 | 1 | x | 0 | 0 | 1 |
| 0 | 1 | x | x | 0 | 1 | 0 |
| 1 | x | x | x | 0 | 1 | 1 |
2. Use logic gates to implement the encoder circuit.
(Need to know of table is right before I start building circuit)
