Test 2: Analog and Digital Electronics

Question 1

The output of a two inputs NOR gate is '1', when:

• AA is '1' and B is '0'
• BA is '0' and B is '1'
• Cboth A and B are '0'
• Dboth A and B are '1'

Question 2

The output of a NAND gate is '0', when:

• Aboth of its inputs are '0'
• Bboth of its inputs are '1'
• Cany of its inputs is '0'
• Dany of its inputs is '1'

Question 3

How many bits make up a byte in Boolean logic?

• A2
• B4
• C6
• D8

Question 4

In analog circuits, voltages and currents:

• Ahave only two values
• Bvary smoothly and continuously within a certain range
• Care always zero
• Dare always constant

Question 5

In digital circuits, voltages have only two values called:

• Apositive and negative
• Bhigh and low
• Cred and blue
• Dnorth and south
