1. A transducer assembly for connection with an external digital signal processing system, said transducer assembly comprising:

  • an analog transducer;

    a digital connector assembly movable relative to said analog transducer to facilitate connection with the digital signal processing system; and

    a cable permanently affixed between said analog transducer and said digital connector assembly to convey an analog signal therebetween;

    wherein said digital connector assembly includes;

    a connector housing;

    a digital connector mounted by said connector housing to mate in a detachable manner with the digital signal processing system; and

    transducer interface circuitry disposed within said connector housing in a non-removable manner and including;

    a digital storage device programmed to hold digital calibration and correction data for said transducer;

    a microprocessor for retrieving said calibration and correction data from said digital storage device and generating digital corrections; and

    signal conditioning circuitry for receiving an analog transducer signal from said analog transducer and said generated digital corrections from said microprocessor and for applying said generated digital corrections to said analog transducer signal to produce a conditioned transducer signal for transmission to the digital signal processing system.
