The output of a 2-input AND gate is fed to a NOT gate. Give the name of the combination and its logic symbol. Write down its truth table.
The output of a two input NOR gate is in state 1 when :-
Draw the symbol for AND gate and write its truth table.
Using the wave forms of the input A and B, draw the output waveform of the given logic circuit . Identify the logic gate obtained . Write also the truth table.
The output of an OR gate is connected to both the inputs of a NAND gate. The combination will serve as a
Draw a sumbol for NOR gate and write its truth table.
The output of the given logic gate is 1 when inputs A,B and C are such that :-
What is a NAND gate ? Write its truth table.
What is the symbol of a NOR gate? Write its truth table.
The inputs A and B are inverted by using two NOT gates and their outputs are fed to the NOR gate as shown: Analyse the action of the gates (1) and (2) and identify the logic gate of the complete circuit so obtained. Give its symbol and the truth table.
