    摘要: A semiconductor chip (CHP) and a semiconductor chip driver (RDR) communicate with each other in a wireless fashion. To that end, the semiconductor chip driver (RDR) generates an energy flux (FX1; FX2) that is concentrated on a transducer area (AT1; AT2) of the semiconductor chip (CHP). In the semiconductor chip (CHP), a wireless communication interlace (WCI) provides an electrical signal to a signal processing circuit in response to the energy flux (FX1; FX2). The signal processing circuit occupies an area (AS) that is substantially separate from the transducer area (AT1; AT2) on which the energy flux (FX1; FX2) is concentrated.

    摘要: Sigma-delta modulation is provided, comprising feeding an input signal to a first SDM, subtracting the output of the first SDM from the input signal, filtering the output of the subtracting to obtain a filtered signal, delaying the input signal, adding the filtered signal to the delayed signal, feeding the output of the adder to a second SDM and providing the output of the second SDM. The first SDM in combination with the subtracting and filtering delivers a correction signal which, by adding it to the input signal, reduces the distortion in the second SDM, which second SDM performs in fact the sigma-delta modulation of the device.

    摘要: An audio coding scheme allowing PCM signal to lossless DSD signal expansion for next generation optical disc formats. The method of encoding an input DSD signal includes up-sampling a corresponding PCM signal to the DSD sample rate. Then a set of loop filter parameters for a noise-shaping loop of a sigma-delta modulator are generated, either using a random starting condition of the sigma-delta modulator or including synchronization parameters. This will allow a decoder to regenerate an almost perfect signal, but still it needs a correction signal to be able to bit identically regenerate the DSD input signal. Therefore, a correction signal is generated based on a difference between a sigma-delta modulated version of the up-sampled PCM signal and the input DSD signal, wherein the sigma-delta modulated version of the up-sampled PCM signal is obtained using the set of loop filter parameters. The correction signal may be adapted to be applied to the low bit PCM signal, to the up-sampled PCM signal or to the output bit stream. Finally, an expansion bit stream is generated where an encoded version of the set of loop filter parameters and an encoded version of the correction signal are included. The decoder can reproduce the original DSD signal based on the already available PCM signal and the described expansion bit stream. Thus, the coding scheme enables top quality audio with minimal storage overhead since the already available PCM signal is used in combination with an expansion bit stream. Since only an additional data stream is required to be stored on a disc, e.g. as part of an MPEG stream, DSD functionality is added to existing systems without causing compatibility problems.
