Title:
DEVICE FOR MODIFYING THE PULSE DUTY FACTOR OR THE PULSE NUMBER DENSITY OF A SIGNAL SEQUENCE
Document Type and Number:
WIPO Patent Application WO/1993/010598
Kind Code:
A1
Abstract:
A device for modifying the pulse duty factor or the pulse number density of a signal sequence has a ramp generator (10) and a first storage (12) with a stored value that predetermines the pulse duty factor or the pulse number density. Output signals of the signal sequence can be triggered when the ramp values produced by the ramp generator (10) exceed or fall below the stored value. A second storage (15) that may receive different stored values for predetermining the pulse duty factor or the pulse number density of the signal sequence is linked to a comparison stage (14) that compares the stored values of the first storage (12) with those of the second storage (15). In addition, means are provided for gradually adapting the stored value of the first storage (12) to the stored value of the second storage (15) when the comparison stage (14) detects a difference. This device allows the pulse duty factor to be automatically and gradually adapted to new conditions, even when these occur abruptly.
