Description
  • The measuring of AE signals needs minimising of a noise and disturbing signals. Usually amplifiers with limited pass-band are used for this aim. Nevertheless the used frequency band is determined in general way empirically. On the other hand, the spectrum of useful signals is determined except of AE source properties by the transfer properties (frequency response) of all mechanical system including the mechanical connecting of AE sensor. Because these transfer properties are variable, therefore it is necessary to measure them for optimum determining of pass-band of AE preamplifier.
