The growing technical advancements in the fields of sensors, instrumentation and signal processing give the opportunity to engineers and scientists to obtain increasingly sophisticated interpretations of their measurements. This talk focuses on the design and interpretation of measurements made on dynamic systems. More specifically, linear time-varying systems are considered. It will be discussed how valuable and sensible information can be extracted from these systems by using well-designed periodic excitation signals and, surprisingly, by interpreting the measurement results in the frequency domain. Intuitive insight into the time-varying character of the system is extracted from visual inspection of the ‘skirts’ that appear in the spectral responses. When considered a disturbance, the time variations are shown to act as frequency correlated noise on the measured signals. When considered a property of interest of the system, a time-varying transfer function of the system is constructed, based on a well-founded system theory. These concepts will be illustrated on simulation and measurement examples.
