Generator for an electrical signal representing a reference curve and analysis apparatus incorporating such a generator, in particular for measuring the humidity content of cereals

摘要

The present invention relates to a generator device for an electrical signal representing a reference curve which comprises a multiplexing member 110, a time base 120 linked to the control terminal 111 of the multiplexing member, in order to successively enable the outputs 112-119 of the latter, a plurality of stages 130 linked respectively to the outputs of the multiplexing member and suitable for generating respective basic reference voltages on associated output terminals 132, at the rate of the enable signals for the outputs of the multiplexing member, means P1 associated with each stage 140 for adjusting the said respective basic reference voltages, and a logic "OR" gate 140 whose inputs 141 are linked respectively to the output terminals of the said stages. Such a generator is usable in particular in apparatuses for measuring the humidity content of cereals. IMAGE
