ABSTRACT:
A diagnostic system for measuring behavior of signals provided by a plurality of sensors (101, 129) includes a plurality of input filters (107, 135) for receiving signals (105, 133) from each of the plurality of sensors (103, 131) and for providing a plurality of filtered sensor signals (109, 137) each derived from the received signals (105, 133). A signal bandwidth of each of the plurality of filtered sensor signals (109, 137) is lower than a signal bandwidth of the than a signal bandwidth of the associated received signal. A selection circuit (119) receives each of the signals (105, 133) from each of the plurality of sensors (103, 131) and, dependent on a selection signal (127), provides a selected sensor signal (121) derived from one of the received signals (105), wherein the selected sensor signal (121) has a signal bandwidth greater than one of the filtered sensor signals (109) derived from the one of the received signals (105).
