1. A vibration meter, comprising:

  • an analog-to-digital converter configured to convert an attenuated vibration signal to a converted signal; and

    a digital frequency enhancement block on which hardware runs various pieces of signal processing software configured to enhance frequency response of the converted signal, the converted signal being amplified by amplifying time domain samples of the attenuated vibration signal to produce an amplified signal, the amplified signal being filtered to produce a filtered signal by a digital high pass filter with a calculated roll-off slope based on an initial frequency of a frequency band within which the frequency response of the converted signal remains somewhat uniform.
