利用MATLAB软件分别设计截止频率为200Hz、采样频率为2000Hz的FIR低通滤波器，滤波器长度为81，并绘出各滤波器的幅度频率响应曲线。(FIR low-pass filters with cut-off frequency of 200 Hz and sampling frequency of 2000 Hz are designed by using MATLAB software. The length of the filters is 81, and the amplitude-frequency response curves of the filters are drawn.)

桌面弹球是游戏中常见的游戏，从以前的掌上游戏机到如今的手机游戏，都是一个十分经典的游戏。玩家控制一个可以左右移动的挡板去改变运动中小球的移动方向，目的是用小球消除游戏屏幕中的所有障碍物到达下一关，在障碍物被消除的过程中，可能会产生一些能改变挡板或者小球状态的物品，例如：挡板变长、变短，小球威力加强等等。本章主要介绍如何实现一个简单的弹球游戏，让读者了解“动画”的实现原理。(Desktop pinball game is common in game, from the previous game boy to today s mobile games, is a very classic game players control a can move around the damper to change the ball movement direction of the movement, the purpose is to use the ball game screen to eliminate all the obstacles and reach the next level, in the process of obstacle is eliminated, may produce some can change baffle or ball state items, such as: baffle get long become short, ball power to strengthen and so on this chapter mainly introduces how to realize a simple pinball game, let the reader know animation principle )
