Claims
- 1. A sensor assembly comprising:
- a) a sensor having an analog output;
- b) an analog-to-digital converter having an analog input side operatively connected to said analog output, having a sampling interval, and having a digital output side yielding a digital output for each said sampling interval; and
- c) a filter having an input side operatively connected to the digital output side of said analog-to-digital converter and having an output equal to the sum of the products of said digital outputs and associated fixed filtering coefficients, said sum taken over a predetermined number of said sampling intervals, and said fixed filtering coefficients being set equal to filtering coefficients adaptively-determined such that said output of said filter generally matches a reference digital output from a reference sensor.
- 2. The sensor assembly of claim 1, wherein said sensor comprises a pressure transducer.
