The number of 2 input NAND gates required to design a 4 bit input even parity generator are_______.
12
Open in App
Solution
The correct option is A 12
Thus, to construct a 4 bit input even parity generator we require 3 Ex - OR gates and one Ex - OR gate can be constructed using 4 NAND gates. Thus, total number of NAND gates required =4×3=12.
