TL431提供恒定偏流的电桥 TL431提供恒定偏流的电桥 (TL431 provide a constant bias current of the bridge to provide a constant bias current of the TL431 bridge)

本课设完成的是任意信号卷积的运算,并且绘制图象.(For the completion of this lesson is that any signal of the convolution operator, and rendering images.)

数字基带系统将数字信号从时域上看时数字滚降，需要画出滚降前后的波形展示出来。频域上带宽变化了。输入滤波器之前的波形与采样判决之后的波形。采样判决前的频谱。 采样判决后的码型。 2、眼图（采样判决之前的眼图）（信噪比大眼图清晰） 3、误码曲线，（横坐标时信噪比，纵坐标时误码率） 4、Arfa变化对误码特性的影响，变好还是变差(变好)，眼图清晰度变化（清晰），传递函数的带宽的变化。（带宽越大）(1.Digital baseband system point of view the digital signal from the time domain when the number of roll-off, you need to draw the waveform displayed before and after the roll-out. The frequency domain, the bandwidth change. Input filter and sample ruling before the wave after wave. Sample pre-judgment spectrum. Sampling pattern after the verdict. 2, the eye diagram (eye before sampling decision) (SNR big eye clear) 3, the error curve (abscissa when the signal to noise ratio, bit error rate when the vertical axis) 4, Arfa impact of change on BER performance, get better or worse (getting better), change of eye-definition (clarity), the transfer function of the bandwidth changes. (The greater the bandwidth))

Schrittzahl in Iteration errorcode = 2: Max. Schrittzahl in Backtracking errorcode = 3: x nicht zulaessig

语谱图程序，用于语音信号分析。实现获取基音周期，区分清音、浊音等功能(Spectrum language program for speech signal analysis. Achieve access to the pitch period, the distinction between voiceless, voiced etc.)

基于趋近律的滑模鲁棒控制 一个系统仿真实例(Reaching Law Sliding based robust control Simulation examples)

传统的DOA估计算法，如MUSIC、ESPRIT算法，都是在假设信号没有相干的情况下求解的，一旦信源信号具有相干性，估计性能会急速下降，所以提出了空间平滑的算法，解决相干信号的波达估计！(The traditional DOA algorithms, such as MUSIC, ESPRIT algorithm, is under the assumption that the signal is not coherent case solving, once the source signal with coherence, estimation performance will fall, so put forward spatial smoothing algorithm, to solve the coherent signal estimation of direction of arrival!)

用于水印检测，确定是否存在水印，对水印的产生也有一次的帮助(For watermark detection, to ascertain whether there is a watermark, the watermark also have the help of a)

用matlab做的简易小钢琴，鼠标点击即可播放音乐(Using matlab to do a simple piano, mouse click to play music)

在模式识别中，样本的特征选取是很重要的，大大的影响识别率，样本的特征提取(In pattern recognition, feature selection of samples is very important, and greatly affect the recognition rate, sample extraction)
