霍夫曼编码n元编码，可以计算出平均码长，编码效率(Huffman coding n-ary coding, can calculate the average code length, coding efficiency)

composite material lamina

仿真信号的FFT频谱和功率谱，绘制了emd分解结果，以及瞬时包络和瞬时频率图，还有Hilbert-Huang谱和Hilbert边际谱。(The FFT spectrum and power spectrum of the simulated signal, the emd decomposition results, and the instantaneous envelope and instantaneous frequency maps, as well as the Hilbert-Huang spectrum and the Hilbert marginal spectrum.)

SPEED CONTROL OF DC MOTOR

均匀量化和非均匀量化在性能上存在着显著的差异，这种差异可以用信号通过量化器后的量躁比来反映出来。本程序用曲线表示了理论和实际两个方面下两种量化的量躁比。从而可观察他们的性能上的差别。(There are significant differences with the function between Uniform quantization and non-uniform quantization ,which can be quantified by SNR from the quantizer.This program use the curves to denote the SNR of theory and practical signal.Then we can observe the performance of the differences.)
