The problem describes a logic circuit with inputs $x$ and $y$. The circuit consists of a NOT gate applied to $x$, and the output of the NOT gate and $y$ are inputs to an OR gate, producing the output $F$. We are given a truth table with values of $x$ and $y$ and must determine the corresponding values of $F$.

1. Problem Description

The problem describes a logic circuit with inputs xx and yy. The circuit consists of a NOT gate applied to xx, and the output of the NOT gate and yy are inputs to an OR gate, producing the output FF. We are given a truth table with values of xx and yy and must determine the corresponding values of FF.

2. Solution Steps

First, analyze the logic circuit. The NOT gate inverts the input xx. The OR gate outputs a 1 if either of its inputs is 1, and 0 if both inputs are

0. Let $x'$ denote the output of the NOT gate, which is the inverse of $x$. Therefore:

x=¬xx' = \neg x
The final output FF is given by:
F=xy=(¬x)yF = x' \lor y = (\neg x) \lor y
We will apply this formula for each combination of xx and yy.
Case 1: x=0x = 0, y=0y = 0.
x=¬0=1x' = \neg 0 = 1.
F=10=1F = 1 \lor 0 = 1.
Case 2: x=0x = 0, y=1y = 1.
x=¬0=1x' = \neg 0 = 1.
F=11=1F = 1 \lor 1 = 1.
Case 3: x=1x = 1, y=0y = 0.
x=¬1=0x' = \neg 1 = 0.
F=00=0F = 0 \lor 0 = 0.
Case 4: x=1x = 1, y=1y = 1.
x=¬1=0x' = \neg 1 = 0.
F=01=1F = 0 \lor 1 = 1.
The correct order of the truth table values for FF is 1,1,0,11, 1, 0, 1.

3. Final Answer

(2) 1,1,0,1
