simulation of pwm converter

OFDM signal generation using MATLAB. Input to the function are Alphabet size, cyclic prefix length, and number of active subcarriers and total subcarriers

说明：  切削力随着磨削深度、速度的增大的趋势，这对于切削过程来说是非常重要的，如果增加相应的参数，就会导致不同的结果(The cutting force increases with the grinding depth and speed, which is very important for the cutting process. If the corresponding parameters are increased, the results will be different)

利用matlab求一段语音信号的时域能量以及频域能量(Demand a voice signal using matlab in time domain and frequency domain energy energy)

利用小波变换多尺度分析的特性,在小波域的各个尺度上选取不同的阈值对基本的频域谱减法进行改进,并且根据清浊音各自不同的特点,在去噪过程中加以分离,保留了语音中的清音成分,使语音更加饱满。(The use of multi-scale wavelet analysis of the characteristics of the individual in the wavelet domain scale threshold select a different frequency domain of the basic spectral subtraction to improve and, in accordance with their respective Qingzhuo sound different characteristics, in the denoising process be separated from the retained voice of the voiceless in the composition, more full of voice.)
