说明：  平均周期图法和平滑平均周期图法估计功率谱 从经典功率谱估计周期图法原理入手，从理论上分析了其存在的局限性，借助Welch算法对其进行修正。依靠Matlab强大的数值分析和信号处理能力进行实验!! 用周期图法和welch法分别估计了一下信号的功率谱密度。采样频率200Hz，时间序列长度2048，FFT数据点数2048。其中welch法使用hanning窗，窗口长度600．(Average periodogram and periodogram smoothing method to estimate the average power spectrum from the classical power spectrum estimation periodogram principle starting from the theoretical analysis of the limitations of its existence, with the Welch algorithm, amending them. Rely on the powerful Matlab numerical analysis and signal processing capabilities to experiment!! With periodogram and welch method were estimated signal power spectral density about. Sampling frequency of 200Hz, the time sequence length 2048, FFT data points 2048. Welch method which uses hanning window, the window length of 600.)

应用matlab，仿真雪花飘飞，非常的逼真直观(Application of Matlab simulation snowy, very realistic and intuitive)

this is watermark source code. it is good for making programming

This paper starts by analyzing the modulation requirements of a single-phase H-bridge -source inverter, and subsequently extends the analysis to cover the more complex three-phase-leg and four-phase-leg -source inverters, with carrier-based implementation reference equations derived for all the inverters. The theoretical and modulation concepts presented have been verified both in simulation and experimentally.(This paper starts by analyzing the modulation requirements of a single-phase H-bridge-source inverter, and subsequently extends the analysis to cover the more complex three-phase-leg and four-phase-leg-source inverters, with carrier-based implementation reference equations derived for all the inverters.
