<p>A procedure for comparing an input signal with different voltage thresholds in a flashing circuit with flashing lamps involves the steps of using a control unit (41) to supply control signals to a threshold generator circuit (40) and by each control signal, the threshold generator circuit is caused to generate a certain voltage threshold. Then the input signal and the respective voltage threshold are passed to a comparator circuit (37) and compared with one another and the result of the comparison is passed to switching parts wired in afterwards for further processing.</p> |
