| Abstract: | This paper presents a new digital linearization principle for realizing the linearization of exponential and natural logorithm transducers by utilization of the strict exponential characteristic of charge-discharge of R-C active network. The linearization accuracy is high; the range of dynamic measurement available is wide and it is capable of direct output of pulse width and frequency signals. |
