Experiments Included:

  • Study of Delta Modulation / Demodulation
  • Study of Adaptive Delta Modulation and Demodulation
  • Study of Delta Sigma Modulation and Demodulation

In Digital Communication specially operating at low frequencies or for speech communication bandwidth can be saved using Delta Modulation and its associated techniques because this requires single encoding of sampled signal. This Trainer covers Delta, Adaptive Delta and Delta Sigma Modulation and Demodulation.
