The figure shows two $NAND$ gates followed by a $NOR$ gate. The system is equivalent to the following logic gate:

In which of the logic gate the following statement is true? "The output is high when either of the inputs is high but not if both inputs are high"

$A$ $NOR$ gate and a $NAND$ gate are connected as shown in the figure. Two different sets of inputs are given to this setup. In the first case, the inputs to the gates are $A=0, B=0, C=0$. In the second case, the inputs are $A=1, B=0, C=1$. The output $D$ in the first case and second case respectively are

Converting the binary number $1011.01$ into decimal gives ....

If $a, b, c, d$ are inputs to a gate and $x$ is its output,then,as per the following time graph,the gate is

The values of $Y$ and $Z$ in the given logic circuit are
