FM_phase_noise_1
The file calculates and plots FM noise sidebands for a carrier. It also does sinusoidal modulation. This simple way of adding noise to a carrier is useful for simulation of PLLs. It turns out, though, that the mean of the randn function is not as close to zero as it could be, and this causes the fft to generate extra sideband energy, which makes it appear as if the noise is not what would be expected. This program gets around this by adding a fudge factor to the randn results to eliminate this problem. It took me ages to figure this out, I hope to reduce a similar effort for others

采用动态加权综合评价方法建立评价模型，增大了评价结果的客观性。首先对评价指标数据进行归一化处理，然后选取偏大型正态分布函数作为动态加权函数建立评价模型，从而对评价指标观测值进行排序，最后用决策(Dynamic weighted comprehensive uation method to establish uation model, increasing the objectivity of uation results. First uation data normalization, and then the partial large normal distribution function as a dynamic weighting function uation model, and thus the uation observations are sorted, with the final decisions)
