    Abstract: An isolator includes a transmitter, a coupling module and a receiver. The transmitter drives an input of the coupling module in response to a digital signal, such that in response to a first type of digital data value in the digital signal, a signal of a first predetermined type is supplied to the input and in response to a second type of digital data value in the digital signal, a signal of a second predetermined type is supplied to the input, the signals of the first type and the second type each including an initiation signal that announces a time window during which another portion of the signals representing a digital data value of the first type or the second type will be valid. The receiver is coupled to an output of the coupling module to receive and to decode signals in correspondence to the signals provided to the input.

  • Patent number: 7577408
    Abstract: A method is proposed for signal processing with predistortion. An amplifier circuit is provided for this purpose, whose operating states are characterized by at least one characteristic variable. A digital modulation signal having two components (R, ?), as well as a power word (LS), derived from the first component (R), are produced, and an operating state of the at least one amplifier circuit is then determined by recording of the characteristic variable. The power word (LS) is compared with the reference value and used to decide whether to predistort the first and/or the second component. A table with various predistortion coefficients is selected from at least two tables, depending on the operating state of the amplifier circuit. One predistortion coefficient is then determined from the selected table with the produced power word (LS) and the first component (R), and the predistortion coefficient is used for predistortion.

  • Patent number: 7461324
    Abstract: Depending on the sequence of the decoded payload signal bits (am1, . . . , amA) and redundancy checking bits (pm1, . . . , pmL) which are produced by the Viterbi traceback, either some of these bits are inserted by means of a distribution device (1) from the front into a linear feedback shift register (10), or some of these bits are inserted by means of the distribution device (1) from the rear into a linear feedback shift register (10), or all of them are inserted into a linear feedback shift register (20) from the rear with the allocated coefficients being unchanged, or all of them are inserted into a shift register from the front with the allocated coefficients being inverted. This allows a redundancy checking process to be carried out on a transmitted data block in the shift register (10; 20) without temporary storage of the bits produced by the decoding process.

  • Patent number: 7446557
    Abstract: In order to generate a control signal for adjusting a driver stage with an adjustable output impedance, an impedance signal is generated for a measure of the output impedance of the driver stage. The difference between the impedance signal and a reference signal is calculated, and passed to a sigma-delta modulator to generate a digital bitstream signal. The control signal is then generated depending on the bitstream signal, where the frequencies of the two signal states in the bitstream signal are evaluated by means of digital counters. Depending on the difference of the determined frequencies of the two signal states, a counter is increased or reduced, and the control signal is generated depending on the count of the counter. The impedance signal may be generated by a replica circuit of a pull-up region or a pull-down region of the driver stage to be adjusted.
