Symbolic representation of four logic gates are shown as
Pick out which ones are for AND, NAND and NOT gates, respectively.
Pick out which ones are for AND, NAND and NOT gates, respectively.
A
(ii), (iv) and (iii)
B
(ii), (iii) and (iv)
C
(iii), (ii) and (i)
D
(iii), (ii) and (iv)
Detailed Solution
In the figure, (i) is the OR gate symbol (curved input side, pointed output).
(ii) is the AND gate symbol (flat input side and a semicircular, D-shaped output side with no bubble).
(iii) is the NOT gate symbol (a triangle with a small bubble at the output and a single input).
(iv) is the NAND gate symbol (the AND symbol followed by a small bubble at the output).
So AND, NAND and NOT gates are (ii), (iv) and (iii) respectively.
(ii) is the AND gate symbol (flat input side and a semicircular, D-shaped output side with no bubble).
(iii) is the NOT gate symbol (a triangle with a small bubble at the output and a single input).
(iv) is the NAND gate symbol (the AND symbol followed by a small bubble at the output).
So AND, NAND and NOT gates are (ii), (iv) and (iii) respectively.
