Assignment 02

目的：　Fourier変換のしくみを理解し、実際に波をスペクトル解析することで波の周波数特性をについて 考える。

内容：　以下の波をFourier変換し波の特性を周波数領域から考察してください。

ⅰ)　以下の形状をもつ波をフーリエ変換し波の特性を考察しなさい。ただし、サンプリング周期

tを変化させて得られるスペクトル特性を比較しなさい。

ⅱ)　実際の地震波や計測された波（どんな波でもOK）についてその周波数特性を考察しなさ い。

Purpose: the purpose is to understand the procedure of Fourier transformation and learn the way to discuss properties of wave on the basis of analysis not only time in domain but also in frequency domain.

Subjects: Discuss the properties of some waves by Fourier transformation with account for characteristics in frequency domain.

ⅰ)　Discuss the frequency properties of samples waves by Fourier transformation. Here, set up sampling interval t to be any value by your-self, and use different values and compare the results.

ⅱ)　Analyze frequency properties of real earthquake or waves sampled (any waves).

---ⅰ)　sample waves

In particular, we discuss the connection between different approaches to the analysis of such equations and the associated indices, which are the differentiation index and the strangeness index

The approach based on the strangeness index includes un- determined solution components but requires a number of constant rank conditions, whereas the approach based on
