Parameter estimation and error aanalysis of forecasting model of exponential curve 指数曲线预测模型的参数估计与误差分析
The second one is a brand - new method based on dual - exponential curve transformation 第二种则是依据一个称为双指数曲线转换的全新方法。
By utilizing the inherent exponential curves , high - linearity components are not necessarily required and the design efforts are relaxed 由于采用的是最自然的指数曲线,所以我们的线路可以不需要高线性度的元件,因而降低了设计上的难度。
Work of this sort follows an exponential curve , where the initial work is painfully slow , and then accelerates rapidly when the technical dictionary and standards are well established 这样的工作表现为一条指数曲线,开始的工作极为缓慢,然后在技术词典和标准建立后迅速地加速。
Furthermore , the dual - exponential curve transformation needs no reference time intervals for calibration , and hence it immunes to the uncertainties such as jitter of the reference inputs 更重要的是,双指数曲线转换的方法不需要参考的时间单位来作为校正输入,因此可以避免参考时间的不确定性如时基抖动所造成的误差。
