Give the symbol, and the truth table, of each of the two logic gates, obtained by using the two circuits, shown below.   

Answer:

                    (a) The circuit of Fig. (a) represents OR gate                                         Logic symbol of OR gate. Truth table of OR gate

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

                     (b) The circuit of Fig. (b) represents AND gate. Logic symbol of AND gate. Truth table of AND gate

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