Question
Download Solution PDFA combinational logic circuit for traffic control is designed. ___________ GATE can only be used to implement the designed control circuit without any additional GATES.
Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFThe logic gate for traffic control is:
| Input J | Input K | Red Light X | Yellow Light Y | Green Light Z |
| 0 | 0 | 1 | 0 | 0 |
| 0 | 1 | 1 | 1 | 0 |
| 1 | 0 | 0 | 0 | 1 |
| 1 | 1 | 0 | 1 | 0 |
For red light
Output X = NOT (J)
For yellow light
Output Y = K
For green light:
Output Z = J AND (NOT K)
Combined Circuit is given as,
Now, all the gates can be formed from NAND gate, as it is a universal gate.
NAND gate will be the correct answer.
