Logic Gates

The symbolic representation of four logic gates are given below

The logic symbols for OR, NOT and NAND gates are respectively

Show answer and solution

Answer: (b)

(i) D-shape with bubble: NAND; (ii) triangle with bubble: NOT.
(iii) D-shape without bubble: AND; (iv) curved input, pointed output: OR.
OR, NOT, NAND = (iv), (ii), (i): answer (b).
