21. A NAND gate consists of an AND gate and an OR gate connected in series with each other.
- TRUE
- FALSE
22. In an expression containing both AND and OR operations, the AND operations are performed first (unless parentheses indicate otherwise).
- TRUE
- FALSE
23. 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.
- TRUE
- FALSE
24. A minimum of three universal NOR gates would be required to perform the logical operation of a 2-input AND gate.
- TRUE
- FALSE
26. Output logic levels for certain input conditions of a logic circuit may often be determined without using the Boolean expression.
- TRUE
- FALSE
28. The output of a NAND gate is the inverse of the output for an AND gate for all possible input combinations.
- TRUE
- FALSE
