    摘要: A digital control circuit with a device for generating a high-resolution tuning voltage is suitable for use in receivers for RF signals, particularly in consumer equipment. The tuning voltage can be electronically switched from one value to another at a high speed. The transient time required with conventional control loops is nearly eliminated since the low-pass filter or the digital integrator is preset to its steady-state integration value. To generate the tuning voltage, dynamic digital-to-analog convertors are provided which, despite their high resolution, require only a smoothing filter with a short response time and a short time constant.

    摘要: In an electrooptical arrangement for remotely controlling an electronic apparatus with a remote control transmitter, the transmitter is formed with three sources of radiation whose radiation patterns are different from each other and can be comparatively detected relative to each other to indicate the tilting of the transmitter in different reference plane directions. A radiation detector at the receiver side detects the different radiation intensities for the signals from the three sources, and the relation between the signal intensities is evaluated to determine the tilt angles of the remote control transmitter in the reference plane directions.

    摘要: A measuring apparatus for detecting a relative movement between at least one magnetic field sensor array integrated into a semiconductor chip and a transmitter for the sensor array is provided. The transmitter and the sensor array are exposed to the magnetic flux of a magnet. The transmitter has teeth that can be moved past the sensor array during the relative movement, or the transmitter has magnet poles that can be moved past the sensor array during the relative movement. The magnetic field sensor includes a differential magnetic field sensor which comprises a first measuring plate and a second measuring plate that are offset in relation to one another in a direction of the relative movement. The magnetic field sensor also includes a sensor element which is designed to measure the absolute magnetic field and comprises a third measuring plate that is arranged between the first measuring plate and the second measuring plate in the direction of the relative movement.

    摘要: In a method for generating pulse edges, assigned synchronously to the movement of a mechanical part, a magnetic field is generated. At least two measuring signals phase-shifted to one another for the magnetic field are detected. The magnetic field is changed as a function of the movement of the mechanical part in such a way that the measuring signals are modulated. A first measuring signal is compared with at least one first reference value. A second measuring signal is compared with at least one second reference value and/or the value of the first measuring signal is compared with the value of the second measuring signal. When at least one of these comparisons produces an agreement or the result of the relevant comparison changes its sign, a pulse edge is generated.

The a digital data input, a converter voltage output, a voltage controlled oscillator, and a pulse width modulation module is configured in a controllable manner for converting digital data received at the input to a converter output voltage at the output using a reference voltage, an adjustable current as a reference current, and an adjustable impedance value. The circuit layout is characterized in that the voltage controlled oscillator includes circuit components which multiply the reference voltage by a quotient between the adjustable impedance value and the adjustable current, and which apply the multiplication results to the pulse width modulation module.

    摘要: A master-slave data transmission system employs a flexible single-wire bus and where any master unit can send data to or read data from any slave at a single time. Data transfer is accomplished by means of a flexible message format having a variable-length address section and a variable-length data section, with the beginning and end of the individual message sections being defined by labels, and a fixed bit clock being transmitted for a given interval before and/or after the message. During multiple master operation, a priority control arrangement prevents two or more masters from accessing the single-wire bus at the same time.
