Description: 本文分析了语音数字信号的采集来源以及其预处理。通过实例，利用Matlab对语音信号进行时频变换与分析，同时构造一个固定频率的干扰信号，对两个信号进行合成，设计数字滤波器，实现对语音信号的F IR、IIR滤波处理，最后在时域和频域中对信号进行分析比较。-This paper analyzes the sources of voice digital signal acquisition and its pretreatment. By example, voice signals using Matlab time-frequency transform and analysis, and construct a fixed-frequency interference signals, the two signal synthesis, design digital filters to realize the speech signal F IR, IIR filtering, and finally time domain and frequency domain signal analysis and comparison.

Description: 利用人体红外和光照强度共同控制灯的开关。晚上有人自动开灯，白天和晚上无人以及晚上有人但睡觉时关灯，晚上睡觉时按一下睡眠开关就能关灯而不受光控和人体红外控制的影响，再按一下又可以灯灭，按了睡眠开关后那光和红外控制不起作用。因而设置了早上八点后自动恢复功能来，让此两种控制起作用，而避免了早上起床后要按开关才能让其起作用的麻烦-The human body and the light intensity infrared light switch common control. Some people automatically turn on the lights at night, day and night but no one was sleeping at night, and turn off the lights at night when lights are turned off by what can sleep without light switch control and IR control of the human body, and can click the lamp, according to the sleep light and infrared control switch that does not work. Thus set up the morning after eight automatic recovery feature, so that the two control work, and to avoid waking up the morning after the switch can be allowed to work according to the trouble of
