摘要： The invention relates to a method and corresponding circuit for pulse redistribution of pwm sensor output data (pi), for example from inertial sensors. The method is characterized in that the scanning interval (s2) of a data processing device, which processes the output signals of one or more sensors, is independent of the length and of the phase position of the limit cycle (s1) or limit cycles (s1) of the sensor(s). In addition, a range transfer of sensors having different working ranges is possible, irrespective of the scanning interval of the data processing device. As a result, incorrect sensor output data can be easily recognized.

摘要： The process as per the invention provides that a digitized real speech signal is converted using complex, preferably Hilbert filtering, into a complex signal that is subjected to a sampling reduction, with the bandwidth of the complex filter matching the sampling rate. The complex signal thus produces is phase-modulated using a code signal generated by a ramdom number generator and is additively combined with a likewise stochastically phase-modulated pilot signal to form a transmissible, scrambled useful signal. The useful signal is transmitted sequentially with a preamble that is used for receiver-side synchronization and equalizing of the useful signal. On the receiver side, again following complex filtering and corresponding sampling reduction during a preamble recognition phase, the digitized received signal is made to yield a clock synchronization for a receiver-side generated, phase-modulated pilot signal, and equalizing coefficients are calculated for a receiver-side equalizer (51), whereupon the phase of the useful signal unscrambling phase is initialized. The scrambled, transmitted useful signal is separated from its transmission-side overlay phase-modulated pilot signal by combining with the synchronized, receiver-side generated pilot signal, and then the resulting phase-modulated, scrambled digital speech signal is unscrambled by unmixing using the code signal generated on the receiver-side and clock-controlled by the preamble.
