程序给出了0~10发音的语谱图,其中采用分帧函数对信号进行分帧处理然后在用fft算法得到频谱信息,后用灰度图像表示(Program gives the pronunciation of words from 0 to 10 spectra, which employs the signal sub-frame function and then in the sub-frame processing spectral information obtained with the fft algorithm, then said with a gray image)

概率潮流计算
说明: 为考查各种不确定性因素对系统运行的影响,需要大量地重复性潮流计算。结合概率理论形成的概率潮流计算能够充分考虑这些不确定性因素。由概率潮流计算可以得到节点电压、电流、支路潮流的均值、方差、概率密度函数等统计特性,从而更全面地反映系统运行状况。(In order to examine the impact of various uncertainties on system operation, a large number of repetitive power flow calculations are needed. The probabilistic power flow calculation based on probability theory can fully consider these uncertainties. Statistical characteristics of node voltage, current and branch power flow, such as mean, variance and probability density function, can be obtained from the calculation of probabilistic power flow, thus reflecting the operation status of the system more comprehensively.)

simulateQSNR
Determine the SNR for a quadrature delta-sigma modulator using simulations.
The modulator is described by a noise transfer function (ntf)
and the number of quantizer levels (nlev).
The ntf/stf may be given in ABCD form.
The band of interest is defined by the oversampling ratio (R)
and the center frequency (f0).
