【Abstract】 The analytic method for solving interval linear equations is improved to meet the demands of circuit worst-case tolerance analysis. Based on the improved method ,fast algorithm and exact algorithm are given for steady-state tolerance analysis. By utilizing the relationship between timedomain analysis and frequency-domain analysis, the method for circuit dynamic-state tolerance analysis is given too. The proposed methods’ advantages lie in their efficiency, practicability and potentialities.更多还原
