2 AnswersEngineering4 years agoFor every possible 4-bit binary number, a full decoder constructed from individual logic gates will require ?
A. 4 individual AND gates for the outputs with 2 inputs each.
B. 16 individual AND gates for the outputs with 8 inputs each.
C. 16 individual AND gates for the outputs with 4 inputs each.
D. 8 individual AND gates for the outputs with 8 inputs each.
Explain why please
2 AnswersProgramming & Design4 years agoA major reason for using digital gates with tri-state outputs is to?
1. allow multiple gates to access a bus at different times.
2. make interfacing with high-current devices easier.
3. disable input data to the gates.
4. allow intermediate logic levels.
1 AnswerEngineering4 years agoQuestion regarding buying wholesale and selling through ecommerce in California?
