ABSTRACT:
The present invention refers to a system for digitally indicating the digital input information, and particularly for avoiding the flickering of the indication state of the indication means in case the input information varies. The system includes a control means for conveying the digital input information to the indication means periodically to update the content of the indication means at the end of a determined period. When input information varies excessively, it is detected and immediately conveyed to the indication means independently of the update at the end of the determined period. Accordingly, the system is quite efficient as an indication system for a continuously varying input information.
