Wide Dynamic Range Acquisition for Ultrasonic Signals
This paper describes our progress in the development of a novel technique of dynamic range expansion we call DRE. The resulting algorithms provide 16 effective bits and a spurious-free
dynamic range of 96dB for most RF digitizers, even those collecting at 5GS/sec or higher. The recorded signals are linear and require no log amplifiers. Log amplifiers may provide acceptable dynamic range yet they introduce undesirable distortion and a significant loss of amplitude resolution.
