Ratio meter control device comprising digital storage means of limited capacity

摘要

The present invention relates to a ratio meter control device characterised in that it comprises means 100 capable of generating a digital signal representing the parameter to be visualised, storage means 310 defining a coding of the numerical signal on the basis of a preestablished law of the sine, cosine or tangent type, the storage means 320 being addressed by intermediate-significance bits of the digital signal, and interpolation means 350 capable of correcting the signal output by the storage means 310 on the basis of the least significant bits of the digital signal.
