POSSIBILITIES TO IMPROVE THE MEASURING PERFORMANCES OF IMPEDANCES IN A WIDE FREQUENCY RANGE

L. Breniuc, M. Cretu, L. Nita
  • Abstract:
    This paper presents our study regarding the possibility of using the nonlinear conversion to measure impedances in a wide range of frequencies. In this case, impedance testing is done by using a multi-frequency signal with the crest factor as low as possible. The non-linear conversion (logarithmic) has as effect measurement error reduction for low levels contained in the measurement signal. From this point of view, non-linear conversion apear to be an alternative to the problem of minimization of the crest factor of the test signal.
