(i) Sketch the output waveform from an AND gate for the inputs A and B shown in Fig. (ii) If the output of the above AND gate is fed to a NOT gate, name the gate of the combination so formed.

Answer:

                    (i) The output of an AND gate is 1 when both the inputs are 1. Hence the output waveform from the AND gate for the inputs A and B is of the type shown below: (ii) A NAND gate is obtained when the output of an AND gate is fed to a NOT gate.
