Abstract: In order to obtain a very close fit to the characteristic curve of a non-linear sensor, such as a thermocouple, a linearized clock is developed and used to increment a counter during a time period representative of the sensor output. The linearized clock is obtained by passing a precision clock signal through a first synchronous binary rate multiplier which receives rate information from an up/down counter. The up/down counter is incremented or decremented by the output from a second synchronous binary rate multiplier which receives rate information from a programmable read only memory in accordance with the segments of the sensor's characteristic curve through which the time scan may be deemed to be passing.
