Arrangement Of Nand Gates Shown Below Effectively Works As

The arrangement of NAND gates shown below effectively works as (a) AND gate (b) OR gate (c) NAND gate (d) NOR gate

Answers:

Correct option  (c) NAND gate

Explanation:

A = 0, B = 0 : gate 1: 1, gate 2: 1, gate 3: 1

 A = 0, B = 1 : gate 1: 1, gate 2: 0, gate 3: 1

A = 1, B = 0 : gate 1: 0, gate 2: 1, gate 3: 1

 A = 1, B = 1 : gate 1: 0, gate 2: 1, gate 3: 0 

 The final output of the logic circuit corresponds to NAND gate.
