Describing Logic Circuits
Boolean Algebra — Associative Law (Addition/OR) Which expression correctly states the associative law for Boolean addition (logical OR), showing that grouping does not change the result?
Digital logic fundamentals — identify the gate with output HIGH when any one input is HIGH Which logic gate produces a HIGH (logic 1) at its output if any one of its inputs is HIGH?
Boolean algebra — identify the correct distributive law identity. Which of the following expressions correctly states the distributive law used in simplifying logic (algebra over {0,1})?
Logic gate notation — what does the small circle (bubble) on a gate output indicate? Choose the operation represented when a bubble is drawn on the output of a logic symbol.
Boolean complement rule: Evaluate the statement: “In Boolean algebra, the complement of 1 is 0.” Support your answer with truth-level reasoning.
Three-input AND expression: Evaluate the statement: “The Boolean expression for a three-input AND gate with inputs A, B, C and output X is X = ABC.”
AND gate output evaluation: Given a 3-input AND gate with inputs A = 1, B = 0, C = 1, determine whether the output will be LOW. Assess the statement.
HDL / text-based description requirement: Evaluate the statement: “In a text-based hardware description (e.g., HDL), the circuit or module being described must be given a name.”
Inverter behavior check: Evaluate the statement: “Applying a LOW to the input of an inverter produces a HIGH at its output.”
Constructing a 2-input AND using only NOR gates: Evaluate the statement: “A minimum of three universal NOR gates is required to realize the logical operation of a 2-input AND gate.”
