noise reduction method

五点三次法实现振动信号趋势项的消除， 1、 计算出数据的均值、均方值、方差 ； 2、 用matlab编制五点三次法消趋势项程序。 3、 在同一坐标下绘出消趋势项前后时域信号，并分析比较。 绘出消趋势项前后信号的自相关函数。( Five points three times a method to achieve the elimination of the trend of the vibration signal, 1, to calculate the mean of the data, the mean square value, variance 2, the preparation of the five points three times France extinction trend procedure using matlab. 3, plotted in the same coordinate consumer trends before and after the time-domain signal, analyzed and compared. Draw to eliminate the trend before and after the signal autocorrelation function. )

capon波束形成器，也称MVDR波束形成器。 它试图使噪声以及来自非θ方向的任何干扰所贡献的功率为最小,但又能保持在观测方向θ上的信号功率不变(capon beam form)

采集到的50Hz电源信号送至信号处理器作为参考信号，该参考信号在信号处理器中需经HILBERT变换变成两路正交正余弦信号X1、X2，然后采用自适应滤波器算法滤掉有用信号中的50Hz信号。(Collected 50Hz power signal to the signal processor as a reference signal, the reference signal in the signal processor requires HILBERT transform into two orthogonal cosine signal is X1, X2, and then filter out the use of adaptive filter algorithm useful signal in the 50Hz signal.)

this program used to acquire data through pc mic with 8khz sampling frequency. it collects data upto 2sec s duration, (can be varied) and reprodued

通过迭代法计算方同轴线的电势分布，进而求得内导体电流，最终计算出同轴线的阻抗(Iterative method to calculate the square coaxial electric potential distribution, and thus obtain the inner conductor current, the final calculation of the impedance of the coaxial)
