Patent ID: 6960954

Claim:
A signal generator comprising: a generator means for producing at least one reference signal; a logic computer, at least one chopping switch, at least one sensor for extracting at least one signal generated in response to the switchings of said at least one switch, means for making a comparison between said at least one extracted signal and at least one reference signal, wherein the logic computer forms a means of control for controlling said at least one switch and designed to deliver on said at least one switch one or more control levels which is or are dependent on the result or results of this comparison or these comparison(s), wherein the means for making a comparison comprising at least one comparator(s) making said comparisons, the logic computer comprising one or more inputs receiving a result of the comparison or comparisons, from said at least one comparator, and the logic computer being programmed so as to update the control level(s) delivered to the chopping switch as a function of the comparison result(s) received, according to a programmable update frequency wherein the programmable update frequency is independent from the results of the comparison which are received on said inputs of the logic computer.
