System making it possible to "raise to the power n" the variations of an exterior quantity such as thermistance, variable capacitance, photoresistance, enhanced-variation self-inductance, etc., characterised by the use of amplification with n stages, the gain at each stage of which varies as a function of an exterior quantity of like nature. The invention therefore applies either to measurements of minimal variations of a quantity, or after calibration to the measurement of a continuous quantity which may be of low value. <IMAGE>
