PDF-Study of effect of Quantization on the signals and systems

Objective Effect of quantization of signals Effect of quantization system Study of law and A law Introduction In digital signal processing quantization is the process of approxim ating a continuous range of values or a very large set of possible dis. We will assume here that the independent variable is time denoted by and the dependent variable could be any physical measurementvariable which changes over time think for example of a time varying electric voltage We will denote the generic measur 1 tr du ti a brPage 2br Fig re brPage 3br 2 Data procedures and rest frames brPage 4br frame brPage 5br Figure 2 brPage 6br Figure 3 brPage 7br Fig re at brPage 8br Fig re brPage 9br 3 The period model and galaxy families tim Lecture 23•Oversampled ADCs–1Bit quantization•Quantization error spectrum•SQNR analysis•Limit cycle oscillations–2order SDDynamic range •Practical implementation CSE 190 [Spring 2015]. , Lecture . 2.

Examples of signals:. Voltage output of a RLC circuit, stock market, ECG, speech, sequences of bases in a gene, MRI or CT scan. Examples of systems:. RLC circuit, an algorithm for predicting future of stock market, an algorithm for detecting abnormal heart rhythms, speech understanding systems, edge detection algorithm for medical images..
