Lecture 4 Quantization Pdf Analog To Digital Converter Sampling Lecture series on digital voice and picture communication by prof.s. sengupta, department of electronics and electrical communication engg ,iit kharagpur . This module addresses dct quantization and its limitations, discussing the trade offs between compression efficiency and image quality in digital communication systems.
Differential Quantization Process And Updation Of Quantization Table Q And not only that the aspects of differential quantization i will be talking again in the perspective of speech communication. but before that we have to continue with our discussions related to the adaptive quantization so we will first be going to that. The lecture discusses sigma delta adcs and strategies to improve a d conversion, including oversampling and differential quantization. it explains the benefits of differential predictive quantization and how oversampling enhances signal to quantization noise ratio. Quantization ideas with weighted quadratic distortion measures have applications outside of traditional data compression, especially to statistical classification, clustering, and machine learning. Lecture 7 : discrete memory less channels : mutual information lecture 8 : channel capacity i lecture 9 : channel capacity ii lecture 10 : channel coding theorem lecture 11 : differential entropy i lecture 12 : differential entropy ii.

To process this redundant information and to have a better output, it is a wise decision to take a predicted sampled value, assumed from its previous output and summarize them with the quantized values. Lecture series on digital voice and picture communication by prof.s. sengupta, department of electr | videos | gan jing world technology for humanity | vi. Sampling by quantizing the difference is called differential quantization. view the qualitative analysis in the sampling & reconstruction course on vru. We introduce the principle we call differential quantization (dq) that prescribes that the past quantization errors should be compensated in such a way as to direct the descent trajectory of a quantized algorithm towards that of its unquantized counterpart.
