A memoryless source has the alphabet A = {-5, -3, -1,0, 1, 3, 5). with corresponding probabilities (0.05,0.1, 0.1,0.15, 0.05, 0.25, 0.3). 1. Find the entropy of the source. 2. Assuming that the source is quantized according to the quantization rule (9(-5)3Dq(-3)%3D -4 q(-1) = q(0) = q(1) =0 9(3) = q(5) = 4 find the entropy of the quantized source.

Estimate the PDF of X = U₁U₂ where U₁ and U₂ are uniform random variables. (Assume U, and U₂ are uniform random variables on the interval [0,1].) Refer to Example 2.1 and the code in Figure 2.7. • Use rng (0) at the start of the script to ensure the same random numbers are generated each time. (Not rand('state',0) as described in the textbook, which is from a previous version of MATLAB.) ▪ Use 1000 realizations. • Use bins centered at 0, 0.1, 0.2, ..., 1. • Save the random variable X in the variable named x (lowercase). • Save the histogram in the variable named h. • Save the PDF in the variable named pxest. Recall that the PDF is the histogram values divided by the total number of realizations, then divided by the bin width. Script> C Reset E MATLAB Documentation
