Abstract:
A data acquisition system for vibration analysis signals includes a logarithmic amplifier for compressing wide dynamic range signals. The logarithmic amplifier replaces attenuators, gain amplifiers, and gain switches used in a conventional system. Further, only a low bit-count analog to digital converter is needed in combination with the logarithmic amplifier. Consequently, the footprint of the system and system cost are reduced.
