Linearisation of TC & RTD


As a novice, I'm not aware of how to linearise a thermocouple or RTD uisng 16-bit delta sigma ADC.

I'm trying to implement this using ATmega16 uC interfaced with ADC using I2C.

Please suggest me a simple algorithm for linearising the thermocouple and RTD using C language.

RTD is quite linear, for

RTD is quite linear, for thermocouple use cold junction and a resistor of appropriate value
