    (54) Analog function generator with electronic linear components


    (57) The invention is relating to the analog function generator with electronic linear components having a function of generating the non-linear function dependence between the input (V 1.1) and the output (V4) of the electronic circuit, exclusively by linear components, and being comprised of two or more operational amplifiers (2, 2.1, 2.n) and the appertaining linear resistors (R 2.1, R 2.2, R 2.n).
    By the analog function generator with electronic linear components we can desirably generate any defined and required function connection, respectively, between the input voltage (V 1.1) and the output voltage (V4) of the electronic circuit,and that,with an extraordinary mathematical exactness with which the influences of the ambient temperature and the heat of the linear components upon the stability and the precisness of the circuit operation are entirely eliminated, with the function generator frequency band-width being extremely enhanced. Due to this the field of application of the analog function voltage generator with electronic linear components is very wide; we can use it with different transducers of non-electric quantities to electric ones: inductive displacement transducers, pressure transducers, NTC and PTC resistors, magnetic converters, optical converters...
