Show the logic symbol and truth table of:
(i) OR gate (ii) AND gate (iii) NOT gate.

Show the logic symbol, Binary equation and truth table for an AND gate.

Write down the symbol and truth table OR gate.

Form AND gate using NOR gates.

What is a NAND gate?

Draw the truth table for NOR gate.

Prepare the truth table of a two input NAND gate.

Prepare the truth table of a two-input NAND gate.

Two digital signals A and B are represented by two binary numbers 110011 and 100110 respectively. These two signals A and B are applied as inputs of (i) OR (ii) AND (iii) NOR and (iv) NAND gates. Find the binary numbers to represent the outputs in each of the four cases.

An OR gate is operated by using positve logic. What role will the OR gate play if we use negative logic? Or, Show that, the truth table of an OR gate in negative logic is similar to that of an AND gate in positive logic.

Prepare the truth table of NOR gate.
