    摘要： A method of producing a record carrier with stored signals thereon and the record made thereby. The method comprises applying to a flexible record carrier hill and dale undulations which correspond to a broadband signal in the form of a frequency modulated carrier frequency oscillation, further applying at least one further signal of lower frequency superimposed on the broadband signal, and selecting an amplitude for the further signal such that in playback of the stored signals by a skid-shaped pickup operating by compression of the hills, even the lowest hills contact the skid-shaped pickup and are compressed thereby.

    摘要： A method of transmitting an audio signal wherein the audio signal is partitioned into successive (in time) blocks by means of time windows, the signal parts contained in the blocks are converted to short-time frequency spectrums by transformation, subsequently the short-time frequency spectrums are coded on the basis of psycho-acoustical masking laws and are transmitted. The received coded signals are decoded, the short-time frequency spectrum signals are brought back into the time domain through re-transformation, and finally the blocks present in the time domain are assembled. Moreover, the blocks are partitioned into sub-blocks and, in case of signal level changes from one block to the other which exceed a predetermined value, the signal parts in the sub-blocks are subjected to a compression prior to transformation and to a complementary expansion after the re-transformation. To improve the signal-to-noise ratio, the signal is amplified and/or attenuated in the sub-blocks during the compression dependent on the average signal powers in the respective sub-blocks.

    摘要： A signal is divided by windows into successive blocks that overlap at least by 50% and signal sections contained in the blocks are evaluated by analysis windows. The signal sections contained in the blocks are subjected to a transformation which permits sub-sampling with compensation of the aliasing components such as, for example, the "time domain aliasing cancellation" method. The spectra resulting from the transformation are subsequently coded, transmitted, decoded after transmission and changed back to signal sections by re-transformation. The blocks including the signal sections are evaluated by synthesis windows and are joined together in an overlapping fashion. The window functions of the synthesis windows are determined in dependence on the window functions of the corresponding analysis windows in the overlap region.

    摘要： To prolong the useful life of a diamond guide element which serves to guide a transducer and which is provided with a contact surface via which the element in use bears against the surface of a record carrier while the carrier moves relative to the element, the element is constructed so that the direction of such relative movement corresponds to a high wear resistance direction of the diamond, and the contact surface thereof is periodically ground in an opposite direction in which it has a lower wear-resistance.

    摘要： The process disclosed enables the "time domain aliasing cancellation" method to be extended systematically to larger block overlapping. The boundary conditions which, when using various modified transforms, the analysis and synthesis windows must comply with, can thus be given. The transform series must also be included in the design of each analysis and synthesis window in order to optimize for a given application, because this changes the boundry conditions with which an analysis window function can be determined. Design for analysis and synthesis windows have shown that analysis and synthesis properties obtained by multiple block overlapping are significantly better than those obtained by convential double block overlapping. The systematic method of the invention offers numerous possibilites for optimizing windows in special applications.

    摘要： A method and apparatus for reducing a resonance peak in a piezoelectric transducer for mechanically recording a signal having a band width of several MHz, in particular on a video disk comprising, applying a countercoupling current across terminals of the transducer for counteracting a current flow in the parallel capacitance of the transducer. A circuit of the invention comprises a piezoelectric transducer having two terminals and including in series a characteristic inductance, capacitance, and resistance, and a parallel capacitance characteristic in parallel to the series characteristic, a signal generator for generating the signal to be recorded, a transformer having a primary winding connected to the signal generator and a secondary winding connected to one terminal of the transducer with a symmetrically disposed central ground connected to the secondary winding. An opposite end of the secondary winding and the other terminal of the transducer are connected to a loading resistor and in turn connected to ground. A compensating capacitor is connected between the other end of the secondary winding and the loading resistor for compensating current flowing through the characteristic parallel capacitance of the transducer. A countercoupling line is connected between the loading resistor and one input of the signal generator so that the countercoupling current may be applied to the signal so as to reduce the resonance peak in the piezoelectric transducer.
