The entire physical size of analog IC is extremely small than that of discrete circuit.

Write value of output $\mathrm{Y}$ in diagram.

You are given two circuits as shown in figure, which consists of NAND gates. Identify the logic operation carried out by the two circuits.

Draw the symbol of a NAND gate and write its truth table.

Draw the logic symbol and give the truth table of the NAND gate. Why this gate is called a universal gate?

Draw the logic symbol of NOR gate.

Show with the help of a diagram, how you will obtain an AND gate using only NAND gates. (Truth table is not required)

Identify the logic gates $\mathrm{X}$and $\mathrm{Y}$in the following figure. Write down the truth table for output $\mathrm{Z}$for all possible inputs $\mathrm{A}$and $\mathrm{B}$.

Identify the equivalent gate and write its name in the circuit shown in the figure. Prepare the truth table of the gate and write its Boolean expression.

What is the output of this combination?
