  • Calibration device, signal processing device, and user interface for the same
    Patent number: 9438357
    Abstract: Calibration device for a signal processing device including an input stage, a signal processing stage and an output stage includes an output stage calibrator. The output stage calibrator includes a test signal source adapted to be coupled to the output stage, a feedback channel connectable between output of the output stage and input of the input stage, and a signal analyzer which couples to the input stage. The test signal source provides a test signal to the output stage which is supplied to the input stage via the feedback channel after processing. The signal analyzer analyzes the test signal after processing by the input stage and determines, based on analysis, deviations of actual output amplification of the output stage at a set output amplification of the output stage and/or deviations of actual input amplification of the input stage at a set input amplification of the input stage.
