Eytan Modiano Slide 1 Sampling Sampling provides a discrete-time representation of a continuous waveform - Sample points are real-valued numbers - In order to transmit over a digital system we must first convert into discrete valued numbers Quantization levels Q3 Q2 Q1 Q3 Q2 Q1 Sample points What are the quantization regions What What What are the quantization levels Eytan Modiano Slide 2 Uniform Quantizer - 3A - A - A L 2 A A 3 A All quantization regions are of equal size A - Except first and last regions if samples are not finite valued With N quantization regions use log2 N bits to represent each quantized value Eytan Modiano Slide
