For the following logic circuit, the truth table is:
\(\begin{matrix} A &B &Y \\ 0&0 &0 \\ 0&1 &1 \\ 1&0 &1 \\ 1&1 &1 \end{matrix}\)
\(\begin{matrix} A &B &Y \\ 0&0 &1 \\ 0&1 &0 \\ 1&0 &1 \\ 1&1 &0 \end{matrix}\)
\(\begin{matrix} A &B &Y \\ 0&0 &0 \\ 0&1 &0 \\ 1&0 &0 \\ 1&1 &1 \end{matrix}\)
\(\begin{matrix} A &B &Y \\ 0&0 &1 \\ 0&1 &1 \\ 1&0 &1 \\ 1&1 &0 \end{matrix}\)
The given logic circuit requires us to determine its corresponding truth table by analyzing the behavior of logic gates in the circuit. From the options provided, we need to identify which truth table represents the function of the circuit.
The circuit's behavior can be represented as a logical expression and then evaluated for every combination of inputs \(A\) and \(B\).
For this particular set of options, the correct behavior of the circuit is captured by the truth table representing the logical AND operation:
A | B | Y |
---|---|---|
0 | 0 | 0 |
0 | 1 | 0 |
1 | 0 | 0 |
1 | 1 | 1 |
Explanation: The AND gate only outputs 1 when both inputs are 1. Hence, the output \(Y\) is 1 only when \(A=1\) and \(B=1\), matching the correct truth table. This option reflects the behavior of a 2-input AND gate.
The correct option is (C): \(\begin{matrix} A &B &Y \\ 0&0 &0 \\ 0&1 &0 \\ 1&0 &0 \\ 1&1 &1 \end{matrix}\)
Y=\(\bar{\bar{A}.\bar{B}}=\bar{\bar{A}}+\bar{\bar{B}}\)

A sphere of radius R is cut from a larger solid sphere of radius 2R as shown in the figure. The ratio of the moment of inertia of the smaller sphere to that of the rest part of the sphere about the Y-axis is :
The current passing through the battery in the given circuit, is:
A bob of heavy mass \(m\) is suspended by a light string of length \(l\). The bob is given a horizontal velocity \(v_0\) as shown in figure. If the string gets slack at some point P making an angle \( \theta \) from the horizontal, the ratio of the speed \(v\) of the bob at point P to its initial speed \(v_0\) is :
It is the gate, where a circuit performs an AND operation. It has n number of input where (n >= 2) and one output.
It is the gate, where a circuit performs an OR operation. It has n number of input where (n >= 2) and one output.
An inverter is also called NOT Gate. It has one input and one output where the input is A and the output is Y.
A NAND operation is also called a NOT-AND operation. It has n number of input where (n >= 2) and one output.
A NOR operation is also called a NOT-OR operation. It has n number of input where (n >= 2) and one output.
XOR or Ex-OR gate is a specific type of gate that can be used in the half adder, full adder, and subtractor.
XNOR gate is a specific type of gate, which can be used in the half adder, full adder, and subtractor. The exclusive-NOR gate is flattened as an EX-NOR gate or sometimes as an X-NOR gate. It has n number of input (n >= 2) and one output.
