DEFINITION

Classification: 374/171

With digital linearizing circuitry:

(under subclass 170) Subject matter having electrical pulse or digital processing circuitry to modify the pulse group content in accordance with the value represented thereby in order to provide an output which is a linear function of the sensed temperature.

(1) Note. The modification is generally the inverse function of the signal relationship to the temperature.
