Abstract: For the manufacture of multilayer actuators, the laminate is split into several actuators, which are pyrolized and then sintered. Because lamination in the unsintered body often produces non-homogeneity in the density, and the shrinkage during the firing of the ceramic is not of a constant value, the final geometry of the actuators can only be accurately obtained by the hardening of the sintered actuators. But in this case the internal electrode layers deposited in the actuators are thereby also processed, which can cause electrical flashovers and leakage currents during operation.

Abstract: Generally, performing sampling-rate conversion from a higher sampling frequency fs1 to a lower sampling frequency fs2 results in aliasing. It is known to use a low-pass filter, known as anti-alias filter, for avoiding this alias distortion. Its effect is to remove spectral contents above fs2/2 from the digital signal. According to the invention these signal parts are suppressed at spectral decoding resulting in a bandwidth of the signal to be re-sampled which is less than half of the second sampling frequency fs2. This can be done for MPEG encoded audio signals by limiting the decoding to a certain number of subbands, for DOLBY AC-3 encoded audio signals by setting certain spectral lines to zero at decoding. The inventive method not only totally removes the processing power needed for calculating an anti-alias filter, but also limits the decoding work needed.
