Give the symbol, and the truth table of each of the two logic gates, obtained by using the two gate combinations, shown in Fig.                                        

Answer:

                    (a) The gate combination of Fig. (a) represents a NAND gate.                                 (a) Logic symbol of NAND gate. Truth table of NAND Gate

Input A	Input B	Output \[\Upsilon \]
0	0	1
0	1	1
1	0	1
1	1	0

(b) The gate combination of Fig. (b) represents a NOR gate. (b) Logic symbol of NOR gate. Truth table of NOR gate

Input A	Input B	Output \[\Upsilon \]
0	0	1
0	1	0
1	0	0
1	1	0
