A digital VLSI implementation of a psychoacoustically and psysiologically motivated preprocessing algorithm is introduced. The algorithm consists of several stages motivated by the signal processing in the human ear and was successfully applied to a wide range of applications by the Medical Physics Group at the University of Oldenburg. The processing scheme(More)
Shock exciters available on the market today suffer from a lack of control of the generated shocks. This paper will present a new type of shock exciter developed by SPEKTRA which is based on the well known HopkinsonBar but using a piezoelectric actuator to apply the force pulse input (* patent pending, [1]). It will be shown that a piezoelectric actuator(More)
