摘要： A technique of decoding erroneous biphase signals is disclosed comprising the following steps. First, phase and magnitude sample values (ps, bs) are formed, from which a first digital signal (d1) is derived. From this, associated bit combinations (St1, St2; Stp) are determined, and a decision is made as to whether the respective bit combination (St1, St2; Stp) is a valid combination (Sg1, Sg2; Sgp) or an erroneous one (Sf1, Sf2; Sfp). Probability values (Sw1, Sw2; Swp) are determined that decide which parts of the erroneous bit combination (Sf1, Sf2; Sfp) are probably true and/or which are probably false. Next, a corrected bit combination (Sk1, Sk2; Skp) is formed from the existing information. Finally, a second digital signal (d2) is generated as an output signal, whose data states are formed either from the valid bit combination (Sg1, Sg2; Sgp) or from the corrected bit combination (Sk1, Sk2; Skp).

摘要： A method utilizing a predetermined set of instructions in a wait routine reduces spurious signals caused by the power consumption of processors, particularly digital signal processors, which is dependent on the instruction code being executed. These spurious signals occur, for example, in processors performing cyclically recurring program routines which are initiated by interrupts where, during the run time of the routines, a first mean power consumption results, and where the run time of the program routines is shorter than the time between two successive interrupts. The cyclic changes in power consumption caused by this mode of operation of the digital signal processor are avoided by performing a wait routine between successive program routines which includes instructions selected to cause a mean power consumption of the processor during the wait routine to correspond to that during the program routines.

摘要： A circuit capable of handling all television sound transmission standards, including the "NICAM" standard. The circuit contains an analog antialiasing low-pass filter which is fed by the analog sound and video signal and followed by an analog-to-digital converter. The output of the latter is freed from the video signal by a filter circuit. The digital sound signal is applied to a phase splitter having a 0.degree. output and a 90.degree. output which are connected to a phase discriminator. An absolute-value output of the phase discriminator provides the amplitude-demodulated sound signal, while a phase-angle output feeds the DQPSK portion of a "NICAM" decoder and a differentiating stage, which delivers the frequency-modulated sound signal.
