5_5 Logic Circuits

What is the equivalent of NAND gate gate?

• (NOT-A + NOT-B)

• (A + B)NOT

• (A.B)NOT

A NOR gate with both inputs inverted becomes a.

• NAND gate

• AND gate

• OR gate

Adding invertors to the two inputs of an AND gate makes a.

• OR gate

• NOR gate

• NAND gate

Which logic gate can be represented as a parallel circuit?

• OR gate

• Exclusive OR gate

• NAND gate

An AND gate output is 1 when inputs are.

• both 1

• both 0

• 1 and 0

What sort of gate requires two positive voltages to operate?

• AND

• OR

• NOT

When will a NAND gate give logic 0 at the output?

• When both inputs are at 1

• When the inputs are different

• When both inputs are at 0

The output of a NOT gate is logic 1. The input is.

• logic 0

• logic 1

• both logic 1

When the voltage that represents a logic 1 state is less than the voltage that represents a logic 0 state, the logic being used is.

• either positive or negative

• positive

• negative

The output of an AND gate having two inputs A and B is logic 1. The two inputs will have the logic states of.

• A = 0, B = 0

• A = 1, B = 0

• A = 1, B = 1
