FIR-filter-design

具体介绍了光伏并网与有源滤波控制原理，以及控制流程，论文结果非常具有代表性，具有较高的参考价值(Specific photovoltaic (pv) grid and active filter control principle are introduced, and control process, the paper the results is very representative, has the high reference value)

估算带宽，先是计算输入信号单边带功率谱密度，然后估算出信号所占的带宽(Bandwidth estimation, first calculating the input signal is single sideband power spectral density, and then estimate the proportion of signal bandwidth)

求解所输入数据的概率分布，可随意设定所分概率区间个数。(Solving the probability distribution of the input data, can be arbitrarily set the number of sub-probability interval.)

BER- 8QAM ,bpsk, QPSK,TRANSMITTED SIGNAL SPECTRUM

基于FFT的比值算法，是用比值法实现的MATLAB程序。 (Based on the ratio of FFT algorithm, is the ratio method using the MATLAB program realize.)

this is an explanation about matpower

此文件介绍了matlab的基础知识，适合于初学者进行学习，希望对大家有所帮助(This document describes the basics of matlab, suitable for beginners to learn, we want to help)
