说明：  （插值） 在某海域测得一些点(x,y)处的水深z由下表给出，船的吃水深度为5英尺，在矩形区域（75，200）*（-50，150）里的哪些地方船要避免进入。 ((Interpolation) measured the waters in a number of points (x, y) the Agency' s water depth z is given by the following table, the ship' s five feet depth of water in the rectangular area (75,200)* (-50,150) in where the ship to avoid.)

说明：  图像摆正，把任意角度的图像摆正Straighten images, straighten out images of the arbitrary Angle(Straighten images, straighten out images of the arbitrary Angle)

说明：   1.录制一段自己的语音信号，并对录制的信号进行采样； 2.画出采样后的语音信号的时域波形和频谱图； 3.给定滤波器的性能指标，采用窗函数法和双线性变换法设计滤波器， 并划出滤波器的频域响应； 4.用该滤波器对采集的信号进行滤波，画出滤波后信号的时域波形和频谱， 并对滤波前后的信号进行对比，分析信号的变化； 5.回放语音信号； 6.设计一个信号处理系统界面(1. Recorded their own voice for some signal, and recording the signal sampling 2. Draw samples of the voice signal after the time-domain waveform and frequency spectrum 3. Given filter performance indicators, using a window function method and dual- Design of linear transformation filters, and draw the filter frequency response 4. to use the filters on the collected signal filtering, after filtering the signal to draw the time-domain waveform and spectrum, and filtering of signals before and after contrast, analysis of signal changes 5. playback voice signal 6. to design a signal processing system interface)
