Ppt Lecture 12 Number Representation And Quantization Effects Analog communication (baseband and modulated) is subject to noise. pulse modulations (pam, pwm, ppm) represent analog signals by analog variations in pulses and are also sunbject to noise. long distance communication requires repeaters, which amplify signal and noise. each link adds noise. Using the high rate approximation for any given tiling, each quantization cell rj has the same shape and area and has a conditional pdf which is approximately uniform. It explains scalar and vector quantization, including the encoding of quantized samples and the calculation of data rates and quantization errors. additionally, it covers optimal uniform quantization and its application in pulse code modulation (pcm). We present definitions of signed and unsigned fixed point binary number representations and develops basic rules and guidelines for the manipulation of these number representations using the common arithmetic and logical operations found in fixed point dsps and hardware components.

Pcm and quantization quantization of a signal produces the closest representable value. for fixed number of values, spacing between values increases with range. Option 1: write a program to perform vector quantization on a gray scale image using 4x4 pixels as a vector. you should design your codebook using all the blocks in the image as training data, using the generalized lloyd algorithm. Another way to characterize the uniform density of the set of exactly rep resentable xed point numbers is to ask this question: given an arbitrary real number r in the interval [rmax; rmin], how near is the nearest exactly representable xed point number?. For the following sequence {1.2, 0.2, 0.5,0.4,0.89,1.3 }, quantize it using a mu law quantizer in the range of ( 1.5,1.5) with 4 levels, and write the quantized sequence.
