① Introduction

The first question is to learn how the theorems of random variables and PDFs are applied to the real life, especially a Laplacian PDF to measure the speech power.
The second question is about quantizing the signal. We will use several type of quantizer. To calculate boundary point and probabilities, we will use conditional pdf that we had learned Lecture 7.
The third question is about random variable estimation. First, we train the program to acknowledge which one is spam mail and test it, which we call Naive Bayes classifier. We apply MAP theorem which is in Lecture 10.
The fourth question is about using Monte Carlo integration, it is useful when the integration is hard to calculate analytically. We had learned it in Lecture 9, 10.

② Problems and Solutions

※ Question 1 : Practical Engineering Problems

A. Setting Clipping Levels for Speech Signals
To determine the highest amplitude of the speech signal that can be expected to occur a common model is to use a Laplacian PDF for the amplitudes [1].
