Differential Quantization and Delta Modulation - VRU

Differential Quantization. Band-limited signals cannot change quickly, so the difference between consecutive samples should be relatively small. Therefore, the difference between consecutive samples 𝗑 (𝑛) − 𝗑 (𝑛 − 1) should be quantized rather than quantizing each raw sample 𝗑 (𝑛). Sampling by quantizing the difference is ...
