Verfahren zur Bildung von einem kodierten RZ oder NRZ Signal

摘要

The method involves synchronizing variations of positive pulse phase and variations of negative pulse phase respectively with rising and decreasing of modulated intensity or vice-versa. The variations of both the phases are approximately symmetric. Width at half-height of the variations of the negative and positive pulse phases is higher or equal to half of the transmission period. - An INDEPENDENT CLAIM is also included for a coding system.
