【Abstract】 This paper describes a method of determining the non-linear coefficient of linear varying voltage. The linear varying voltage is sampled by periodic pulses.The sequent discrete signals are obtained and their amplitude distribution density is measured. Then the non-linear coefficient is calculated by means of linear least squares fitting method. The method of selecting the sampling pulses frequency is provided in this paper also.更多还原
