More Questions from Describing Logic Circuits

• The Boolean expression for a three-input AND gate is X = ABC.
• The inputs to an AND gate are: A = 1, B = 0, C = 1. The output will be LOW.
• In a text-based language, the circuit being described must be given a name.
• A LOW placed on the input of an inverter will produce a HIGH output.
• A minimum of three universal NOR gates would be required to perform the logical operation of a 2-input AND gate.
• In an expression containing both AND and OR operations, the AND operations are performed first (unless parentheses indicate otherwise).
• The effect of an inverted output being connected to the inverting input of another gate is to effectively eliminate one of the inversions, resulting in a single inversion.
• The timing diagram for a two-input NAND gate is shown below. The gate is working correctly.
• A NAND gate consists of an AND gate and an OR gate connected in series with each other.
• The NAND gate is an example of combinational logic.
