摘要： The invention relates to a method of controlling several radiation-emitting elements. The invention consists in the compensation of differences in the emission power of the individual elements due to variations in the efficiency of the elements or to differing operating conditions by operating each radiation-emitting element with an individual pulse length determining the overall emission time. In this way, the energy emitted by all elements triggered is substantially identical.

摘要： A current-to-voltage converter for providing a voltage signal based on a current signal has a first active stage having an input and an output. The first active stage is configured to receive the current signal at its input and provide the voltage signal at its output. In addition, the current-to-voltage converter has a second active stage that is coupled between the output of the first active stage and the input of the first active stage. The second active stage is configured to provide the input of the first active stage with a feedback signal that frequency-selectively counteracts amplification, by the first active stage, of signal components of a current signal applied to the input of the first active stage that have a frequency outside of a prescribed useful frequency band.

摘要： The present invention relates to receiver equipment with AC-coupled receiver circuits and AC coupling filters. A switch connected between a first stage and a second stage among the receiver circuits is adapted to switch from a high coupling corner frequency, for rapid settling of a signal during preparation of data reception, to a low corner frequency, for low signal distortion during data reception. The receiver circuits are adapted to use known properties in the signal to perform the switch at a time when the short term DC-components of the signal are as low as possible.

摘要： The invention is directed to a phase locked loop with a ΣΔ modulator. A multimodulus divider in the feedback path of the PLL is actuated by the ΣΔ modulator. The latter has a design which can be described by a complex transfer function H(s) in the Laplace plane, said transfer function having a complex-conjugate pair of pole points. The arrangement allows a significant reduction in the noise in critical frequency domains and hence allows adherence to transmission masks based on radio specification even when the PLL bandwidth is as large as the modulation bandwidth.
