Question
(i) Sketch the output waveform from an AND gate for the inputs A and B shown in the figure.
(ii) If the output of the above AND gate is fed to a NOT gate, name the gate of the combination so formed.
Solution
(i) The output waveform of AND gate is given below:
(ii) If the output of the AND gate as shown is fed to a NOT gate, the combination so formed will be NAND gate.

(ii) If the output of the AND gate as shown is fed to a NOT gate, the combination so formed will be NAND gate.
