- 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.
