Abstract
The output indications of fluid-filled transducers are compensated by filtering under the control of error analyser signals. In particular, the pressure waveform of a fluid-filled catheter is sampled and used to produce error signals that control a digital filter for the samples in order to compensate for measurement errors that are attributable to the physical characteristics of the catheter.
