Abstract
The invention is related to the field of measurement electronics and related to the measurement of complex transfer functions (e.g. of impedance), especially in the presence of large disturbances and for measuring of small changes of the characteristics of the object under test. The goals of the proposed invention are achieved by detuning of the excitation and reference signals, e.g. by adding incremental phase-shift to the excitation signal to generate the reference signal.
