An NAND gate has an output that is opposite the output of an AND gate.“与非”门的输出是“与”门输出的“反”。? 正确|错误
正确
举一反三
- A NAND gate has an output that is opposite the output of an AND gate
- A NAND gate can be considered as an AND gate followed by a NOT gate.
- A NAND gate works just the same with Negative-OR gate.
- If any input to an OR gate is zero, the output is zero. A: 正确 B: 错误
- For a 2-input NAND gate, output Y is LOW only when both inputs are HIGH,when Y is HIGH when .

- 0
The AND gate output is HIGH only when all the inputs are LOW. A: 正确 B: 错误
- 1
The NOR gate output is LOW when any of the inputs is HIGH. A: 正确 B: 错误
- 2
A 2-input gate produces a HIGH output only when the inputs agree. This type of gate is a(n) A: OR gate B: AND gate C: NOR gate D: XNOR gate
- 3
If any input to an OR gate is zero, the output is zero.
- 4
The output of a OR gate is LOW only when all its inputs are LOW A: 正确 B: 错误
