  • (A) varied, constant
  • (B) varied, varied
  • (C) constant, varied
  • (D) constant, constant
💬 Discuss
✅ Correct Answer: (B) varied, varied

Explanation: quadrature amplitude modulation (qam) is obtained by allowing the amplitude to also vary with the phase. thus, the constellation consists of square lattice of signal points.
