| 摘要 |
<p>The present invention relates to an electronic control circuit (100) enabling a digital control signal (SN) to be processed in order to control at least one potentiometer (P), said electronic control circuit (100) electrically connected to said at least one potentiometer (P) comprising: a distortion circuit (10) configured to distort said signal (SN) in accordance with at least one predetermined distortion datum (DD) in order to obtain two distorted digital signals (SN1', SN2'); a conversion circuit (20) configured to convert each distorted digital signal (SN1', SN2') respectively into first (SA1) and second (SA2) analog signals; a filtering circuit (30) configured to apply a low-pass filter to each analog signal (SA1, SA2); a coupling circuit (30) including two optocouplers (OPT1, OPT2) configured to couple the filtered analog signals (SA1', SA2') and to galvanically insulate the electronic control circuit (100) and said at least one potentiometer (P).</p> |
