- Abstract:
- In the paper a new method for the measurement of R, L, C parameters under non-sinusoidal condition is proposed. The measurement procedure, starting from the consideration that for a non-linear SISO system the discrete transfer function H(z) functionally depends on the applied input, uses the estimated z parameters to obtain the best estimate of the equivalent circuit R, L, C parameters of first and second order systems. The method is implemented by a virtual instrument based on IEEE-1155 and IEEE-488 measurement systems. The realized instrument is vatidated with reference to many experimental results obtained in both on-line and off-line tests.
