Unformatted text preview: x lies in the i th bin. 2. Quantization Example: (a) A random waveform x ( t ) has amplitude uniformly distributed over [1 , 1] . Please provide an optimal 4 bit quantizer for this signal. Show your choice satisFes the LloydMax optimality conditions. (b) Let ˆ x (0) be a quantized sample of the signal level x ( t ) . What is E [ˆ x (0)x ( t )] ? What is E [(ˆ x (0)x ( t )) 2 ] ? What is the probability distribution on the random variable e (0) = ˆ x (0)x ( t ) ? You must justify your results. 1...
