Consider a sequential circuit tocontrol the washer:
The circuit receives 3 input signals: Clock, DoorOpen, andStart. It also maintains a state bit Wash.
If DoorOpen = 1, Wash should be set to 0.
Otherwise, if Start = 1, Wash should be set to 1 and if Start =0, Wash should retain its value from previous cycle.
Make A truth table to compute the new value of Wash;
Make A circuit Diagram.
------------------------------------
How would the truth table look for this problem? I'm confusedabout how the state bit works with the table.
Here's my first attempt:
| Clock | Door Open | Start | Current Wash | Next Wash |
| 0 | 0 | 0 | 1 | 1 |
| 0 | 0 | 1 | 1 | 0 |
| 0 | 1 | 0 | 0 | 0 |
| 0 | 1 | 1 | 1 | 0 |
| 1 | 0 | 0 | 1 | 1 |
| 1 | 0 | 1 | 1 | 0 |
| 1 | 1 | 0 | 0 | 0 |
| 1 | 1 | 1 | 1 | 0 |
I don't know if this is right, let me know what is wrong withthis.
