Patent attributes
A converter of a digital signal into a pulse-width modulated signal, comprising a first conversion unit receiving, at a first frequency, successive digital signals each having one of a first determined number of values, and providing first intermediary signals, at the first frequency, each having one of a second determined number of values smaller than the first determined number; a unit performing a decimation of the first intermediary signals to provide second intermediary signals at a second frequency equal to the first frequency divided by the second determined number minus one; and a second conversion unit providing at the second frequency, from the second intermediary signals, a two-state pulse-width modulated signal having a minimum duration in one of the two states which is equal to the inverse of the first frequency, the first conversion unit receiving the pulse-width modulated signal.
