Question

the diagram below shows a circuit composed of three logic gates labeled or and and. each gate takes two inputs and produces a single output. if inputs b and c are both true, which of the following best describes the final output produced by the circuit? the output will be true regardless of the values of inputs a and d. the output will be true if both inputs a and d are true, and false otherwise. the output will be true if input d is true, and false otherwise.

Explanation:

Step1: Analyze first - level gates

The OR gate takes inputs A and B. Since B is true, the output of the OR gate is true regardless of the value of A (because in an OR operation, if at least one input is true, the output is true). The AND gate takes inputs C and D. Given C is true, the output of this AND gate depends on D. If D is true, its output is true; if D is false, its output is false.

Step2: Analyze final AND gate

The final AND gate takes the output of the first - level OR gate (which is true) and the output of the first - level AND gate. For the final output to be true, the output of the C - D AND gate must be true, which means D must be true.

Answer:

The output will be true if input D is true, and false otherwise.
