Abstract:
1. A triggering unit for triggering state changes in pulse width modulated output signals of a plurality of pulse width modulating channels, the triggering unit comprising: reprogrammable memory for storing first data words which can be used to determine, on a per channel basis, the timings of one or both of a beginning and an end of a respective pulse in a respective one of said pulse width modulated output signals; and a comparator, operatively coupled to the memory, adapted to compare a supplied, timing reference signal to second data that is derived from one or more of said first data words provided by the memory and providing a change-triggering output signal for triggering a change of state in a corresponding pulse width modulated output signal in response to a predetermined comparison condition between the timing reference signal and the second data of the corresponding channel.
