Basic Gates with Interview Quesions


Q. Using two xor gates design as buffer and as inverter?

ANS:

keep A=0 ,B value vary Xor gate  will work as Buffer
  keep A=1 ,B value vary  Xor gate will work as Inverter

Q. How many 2 input XOR gates required implementing 16-bit parity generator?


ANS: Design n-bit Parity Generator using 2-input Xor gate require: (n-1) Inputs .So, 16-bit parity generator require 15  2-input Xor gates.
