In digital transmission modulation technique that requires minimum bandwidth is?

2. PAM
3. PCM
4. Delta Modulation

The modulation technique that requires the minimum bandwidth is Delta Modulation (DM).

Delta modulation (option 4) is a technique that encodes the difference between successive samples of the analog signal, requiring less bandwidth compared to other methods like PCM or DPCM.

Here's a quick breakdown of the other options:

  • DPCM (Differential Pulse Code Modulation): Slightly more efficient than PCM but requires more bandwidth than Delta Modulation.

  • PAM (Pulse Amplitude Modulation): More bandwidth is required than Delta Modulation.

  • PCM (Pulse Code Modulation): Requires more bandwidth than Delta Modulation, as it encodes the actual values of the signal.

Thus, Delta Modulation (option 4) is the correct answer.
