    摘要： In a method for amplitude trimming in transceivers having a PLL circuit operating on the two-point modulation principle, the amplitude of an analog modulation signal is selected on the basis of a modulation shift of a defined digital modulation signal. A predetermined data sequence of the analog modulation signal is applied, the modulation shift of the analog modulation signal is determined, and the amplitude of the analog modulation signal is corrected to match the difference between the modulation shift of the digital modulation signal and the determined modulation shift of the analog modulation signal.

    摘要： A sigma-delta programmer is supplied with a data word having a word length of N bits. The most significant L bits of the data word represent the places before the decimal point, and the remaining N−L less significant bits represent the places after the decimal point in the data word. A sigma-delta modulator is supplied with the N−L+1 less significant bits of the data word. An adder receives the L−1 most significant bits of the data word and a data word that is output by the sigma-delta modulator, and outputs a signal, which is multiplied by the value two by a multiplier.

    摘要： An optoelectronic sensor (10), in particular a laser scanner, is provided which comprises a light transmitter (12) for transmitting a light beam (16) having a beam profile (28) elongated in a line direction into a monitored plane (26), a light receiver (34) for generating a received signal from the light bream (30) remitted by objects in the monitored plane (26), a movable deflection unit (24) for the periodic deflection of the light beam (16, 30) to scan the monitored plane (26) in the course of the movement and an evaluation unit (42) for detecting the objects with reference to the received signal. The laser scanner has an optical beam rotation element (20) which is disposed after the light transmitter (12) and which can tilt the line direction of a light beam (16) passing through.

    摘要： A method for calculating the power consumption of a mobile device, particularly of a mobile station of a mobile radio system, in an observation period Δt based on various possible system states sk in which the device can be in the period Δt. A value of a quantity Δk is determined system-state-dependently for the system states sk occurring in the period Δt. The power consumption in the period Δt is calculated in such a manner that the quantities Δk and state-dependent typical currents ik are taken into consideration.
