Answer C

parity check : EXOR

parity generation : EXNOR

Explanation

Parity generation

  • The XNOR gate will emit 1 only when there is not exactly one 1 input.
  • This feature can be used for parity generation.
  • Suppose A wants to send 1001. XNOR gate will give parity as 0.
  • But if A sends 1000 XNOR gate gives 1 as parity

Parity check

  • B receives: 10010
  • B computes parity: 1+0+0+1+0 (mod 2) = 0 //this can be achieved by EXOR
