摘要： The present invention relates to a generation method of a variation form of an analogue signal generated by a PWM signal whose cyclic ratio and period are programmable. A signal can thus be generated whose evolution is linear over time. A succession of generation steps of a PWM signal during which different period and cyclic ratio values are applied, as well as pairs have different periods with the same cyclic ratio, thus enabling the analogue signal to be varied with great precision. According to an improvement, each generation step of a new PWM signal with different period and cyclic ratio values is applied over time slots of equal time.
The present invention also relates to a generation system of a variable analogue signal implementing the method.

摘要： The present invention relates to a method for controlling the speed of a fan equipping an electronic device and being used to cool it. A speed control value is calculated according to the temperature measured within the electronic device. This command value being limited to a maximum determined value, in such a manner that the fan is not audible. The method comprises a measurement step of the ambient sound level. If the ambient sound level exceeds a determined threshold then the speed of the fan is increased as the ambient sound covers the sound of the fan, even at great speed. An improvement consists in that during the introduction of a sound lowering command, the speed of the fan immediately returns below the maximum value.
The present invention also relates to the device implementing the method.
