We propose the use of blind source separation to en- hance the fault-related machine component in a multi- channel measurement. The feasibility of this approach is demonstrated in two real-world applications. For source separation we use the bilinear forms framework, which allows the combination of several (problem-speci c) separation criteria. In experiments with arti cial data we show that the best performance with either criterion can be approximated by using their combination.
