circonv
圆卷积与线卷积在FIR中的实现,通过程序还开深刻理解两者间的差别和各自优劣。
1.圆卷积用在被截出的某段数据中,此时,长度应该定为和输入数据长度一致(一般输入数据大于hn的数),这时圆卷积结果相当于某段被截断出来的数据以非截断的方式经过滤波而得出的结果;线卷积用在各自独立的,离散的数据中,若截断数据也用线性卷积来计算,那么就相当与这部分数据是与源数据是独立的,
得出的结果时域两端会变长,但频谱基本上一样的。差别可以想象。
2.注意圆卷积最开始的输入数据的次序,构造矩阵时要注意。(Circular convolution with the line convolution in the FIR implementation, the program also opened a deep understanding of the difference between the two and their respective pros and cons. A circular convolution with cut out a certain period of data At this point, the length should be set for the same length as the input data (typically input data greater than hn the number), when the circular convolution is equivalent to a certain the results of the truncated data to the non-truncated filtered line convolution with a separate, discrete data, truncated data with a linear convolution calculation, then the equivalent of this part of the data is independent of the source data, the results of both ends of the time domain becomes long, but the spectrum is basically the same. The difference can imagine. Note that the order of the circular convolution of the input data to construct matrix.)

轴承信号分析
共振解调的过程如下:首先对采集到的信号进行傅里叶变换,然后利用传感器自身的谐振频率进行分析,对滤波后的信号进行包络,包络以后去除了高频部分,得到包络信号,再对改进的包络信号进一步进行低通滤波,最后对最终得到的信号进行傅立叶变换求其频谱图。共振解调的原理及其过程可以用图2 来进行表述。(The process of resonance demodulation is as follows: First, Fourier transform is performed on the collected signal, and then the resonance frequency of the sensor is used for analysis. The filtered signal is enveloped, and the high frequency part is removed after enveloping to obtain an envelope. The signal is further subjected to low-pass filtering on the improved envelope signal. Finally, the spectrum of the resulting signal is Fourier-transformed. The principle of resonant demodulation and its process can be expressed in Figure 2.)
