The thermocouples and some other sensors have an output that is non-linear. That means the mV generated by them are not in direct proportion to the parameter measured. In signal conditioning Linearization can be done with cmos fet switches or even comparators and diodes.
In Embedded Systems Linearization is done with Look-Up tables on ROM and also using Math and Formulae for each segment.
