Digital Electronics LVL 1 Lesson 6

NOT

? logic is any type of gate whose operational output is inverted.

True

A NAND gate can be created by inverting the output of an AND gate, but inverting the inputs to an AND gate is not equivalent.

False

If A = 0 and B = 0, Y = 0.

True

If A = 0 and B = 0, Y = 1.

False

If A = 0 and B = 1, Y = 0.

False

If A = 0 and B = 1, Y = 1.

False

If A = 1 and B = 0, Y = 0.

True

If A = 1 and B = 1, Y = 0.

True

NAND gates are usually more feasible to manufacture than AND gates.

INVERTER

The amplifier used for buffering in a NOR gate is called a(n) ? .

True

The bubble on the NOR symbol indicates that the complement of the OR logic is provided at the output.

universal function

The term ? refers to the fact that the NAND gate can be easily changed into other logic functions such as the INVERTER, AND, OR, and NOR gates.

True

The term NOR is a contraction of NOT and OR

The output would be the complement of the NAND logic and result in AND logic.

What would be the effect on the logic of taking the output from an INVERTER connected after the NAND logic module?

INVERTER

When AND logic is followed by a(n) ? , the output is NAND logic.

I., II., IV., V. only (D)

Which of the following are possible Boolean equations that express the input to output logic of the gate shown?

AB = X

Which of the following is NOT a possible Boolean equation that expresses the input to output logic of the figure?

A

Which symbol represents the NEMA symbol for the 2-input NAND gate?

B

Which symbol represents the NEMA symbol for the 2-input NOR gate?

B

Which symbol represents the conventional symbol for the NAND gate?

C

Which symbol represents the conventional symbol for the NOR gate with three inputs

D

Which symbol represents the new symbol for the NOR gate with three inputs?

All

With AND logic, the output will be HIGH if ? of the inputs are HIGH.
