  • (B) cannot travel long distances
  • (C) its inability to handle analog signals
  • (D) large bandwidth is required for it

✅ Correct Answer: (D) large bandwidth is required for it
Explanation: pulse code modulation (pcm) is a digital form of communication. for demodulation of pcm, it is necessary to convert it into pam. quantization noise occurs in pcm only. its greatest disadvantage is its requirement for large bandwidth.
