  • Physical units in a signal processing system
    Publication number: 20030018673
    Abstract: A method and processing system are disclosed in which a signal acquisition unit is provided for receiving a signal corresponding to a scalar value of a magnitude, and at least one referencing unit is used for correlating a unit object of the magnitude with the scalar value. A processor is provided for processing the magnitude such that a transformation of the scalar value is accompanied by a corresponding transformation of the unit object.

  • Device for collecting analogue measurement signals for the acoustic diagnosis of test pieces
    Patent number: 6347285
    Abstract: Analog test signals may be picked up from the test object with vibration sensors. A computer is equipped with a standard interface card which is connected by an interface, preferably parallel interface, and serves to digitize the test signals. A switching means serves to generate a trigger signal which can be input over a preferably serial interface. An executive routine in the computer switches the input of test signals on and off via the trigger signal.
