  • Method and arrangement for measuring the signal quality in an optical transmission system
    Patent number: 6968134
    Abstract: A received binary signal (BS) is sampled with different thresholds, the sampling results are integrated and stored. The measured probability distributions or probability density distributions can be used to draw conclusions concerning the signal quality (for example, the bit error rate) and to optimize the system.

  • Integrated circuit ring oscillator having line driver with double line feedback
    Patent number: 5652549
    Abstract: A monolithically integrated oscillator is implemented as ring oscillator with a line driver and a double line formed on one and the same chip. A running time of the double line is selected optimally long and a delay time of the line driver is selected optimally short. The double line can be loaded with controllable capacitors.
