  • Method and system for adaptive digital linearization of an output signal from a magnetoresistive head
    Patent number: 5283521
    Abstract: A method and system includes digitally linearizing a digital output signal originating from a magnetoresistive sensor by detecting the digital output signal originating from the magnetoresistive sensor. A linearization factor is then correlated to the digital output signal. Then, the digital output signal is modified the linearization factor to linearize the digital output signal.
