Filed: 1989-02-10
Abstract: PURPOSE:To improve precision in operation by dumping each output in the time combination when the absolute quantity of output is relatively little among the plural outputs in different times and by finding an inductance and a resistance by the use of the electric quantity of each undumped output. CONSTITUTION:Each value of electrical quantity um, lm and rm is once preserved as data. After each absolute value was taken with respect to n-many data um, a mean value umean is found. In comparison of a value epsilon*umean found by this mean value umean multiplied by a designated coefficient epsilon with each absolute value of n-many data, when the absolute value is small, the values um, lm and rm of the times when its um was found are dumped. By the use of the undumped values um, lm and rm, specified processing is performed, where a resistance R and an inductance L are worked out. Consequently, each value of um, lm and rm at a time um 0 is excluded from the specified processing. An operation result with considerable precision can thereby be obtained.
