[LabView] TCP-and-filtering DL : 0: 12、使用TCP的双人或多人聊天程序 13、生成：生成一个由若干个不同频率的正弦波以及均匀分布噪声组成的信号，并显示。（允许用户挑选正弦波个数、设置不同频率、设置幅值、设置信号长度。）保存：将生成的信号保存到二进制文件中。打开：打开二进制文件，并显示。计算：计算并显示功率谱滤波：可以设置滤波种类及滤波频率，可以选择是否滤波。只使用两个Graph，分别用于显示信号和功率谱。（若进行滤波，则只显示滤波后信号和功率谱）-12, Double or multiplayer chat program using TCP 13 generation: to generate a signal noise consisting of several different frequency sine wave, and uniform distribution, and display. (Allowing the user to pick a sine wave number, set a different frequency, set the amplitude, set the length of the signal.) Save: Save the generated signal to a binary file. Open: Open a binary file, and display. Calculation: calculates and displays the power spectral filter: filter types and filter frequency can be set, you can choose whether to filter. Uses only two Graph, respectively, for a display signal and the power spectrum. (If the filtering only display the filtered signal and power spectrum)

[LabView] labview5 DL : 0: 使用低通滤波器从含有噪声的信号中提取有用的正弦波 (见实验指导书实验九数字滤波器中的第一题) 目的：用数字滤波器从含有高频噪声的采样数据中提取正弦信号。要求：①输入信号为一正弦波，并加入一个白噪声的干扰来模拟信号传输中的随机干扰信号（用以模拟含有噪声采样序列）。（模拟含有噪声采样序列具体可用正弦波信号叠加高频噪声来实现，为了使滤波效果明显，本实验的高频噪声是用高频均匀分布白噪声（Uniform）通过Butterworth高通滤波器过滤生成的，高通滤波器的截止频率设为10倍输入信号频率。） ②在程序中设计一个低通巴特沃斯滤波器，以滤除信号中的噪声分量，提取输入的正弦波信号。 ③可调节信号滤波器的截止频率和阶数，可显示滤波前与滤波后的时域信号。 ④给出滤波前与滤波后的频谱特性的显示。 -Using low pass filter extracting useful sine wave signal containing noise(see experiment instruction digital filter in the first nine questions)Objective: to use digital filter sampling data extract containing high frequency noise sine signal.Requirements: (1) the input signal is a sine wave, and add a white noise interference to simulate the random disturbance signal of the signal transmission (to simulate contains noise sampling sequence).(simulated the sampling sequence contains noise available sine wave signal superposition of high frequency noise, in order to make the filtering effect is obvious, the experiment of high frequency noise is Uniform distribution with high frequency white noise (Uniform) by Butterworth high-pass filter to filter generated, high-pass filter cutoff frequency set to 10 times the size of the input signal frequency.)(2) in the program design a low-pass butterworth filter, in order to filter out the noise in the signal component, extract the input sine wav
