Abstract: A signal processing device including a central processing block and plural signal processing function blocks, which are mutually connected by a common address bus and a common data bus, wherein analog signal lines are provided for analog signal transmission between the central processing block and the plural signal processing function blocks and the central processing block is provided with a D/A converter and an A/D converter connected to the analog signal lines. Thus there are only required a D/A converter and an A/D converter in the central processing block, for analog signal transmission between the central processing block and each of the processing function blocks. Also the wiring can be simplified as the number of analog signal lines is limited.

Abstract: A digital signal to be recorded is converted into a digital signal having a suppressed low-frequency spectrum and having a shortest recording wavelength greater than half an original shortest recording wavelength, and the converted digital signal is recorded on a magnetic recording medium in which a plurality of metal evaporated films having different crystal-growth directions are laminated. The digital signal is reproduced from the magnetic recording medium in which the plurality of metal evaporated films having different crystal-growth directions are laminated. Waveform equalization is performed on the reproduced digital signal, and integration detection is performed on the waveform-equalized digital signal, thereby restoring an original digital signal.

Abstract: A video signal processing device is arranged to supply a digital video signal to an infinite impulse response digital filter, to supply the digital video signal from the filter to a look-up table circuit which has a non-linear input-output characteristic, and to emphasize a high-frequency component of the digital video signal by adding the output signal of the look-up table circuit to the digital video signal supplied to the filter, so that a non-linearly emphasizing process can be accomplished at a high speed on the digital video signal. Further, in the video signal processing device, a look-up table circuit is arranged to look up a table by using as an address the output signal of a first subtractor which receives a high-frequency-component-emphasized digital video signal as one of its inputs and to have a non-linear input-output characteristic, the output signal of the look-up table circuit is subtracted from the high-frequency-component-emphasized digital video signal to obtain a high-frequency-component-suppressed digital video signal, the video signal thus obtained is supplied to an infinite impulse response digital filter, and the output signal of the filter is supplied to the first subtracter as its other input, so that the digital video signal can be non-linearly deemphasized at a high speed.

Abstract: A video signal processing device includes first access circuitry for writing a video signal in a memory capable of storing a video signal of at least two picture frames, and second access circuitry for reading the video signal from the memory. Comparision circuitry then compares a first address accessed by the first access circuitry with a second address accessed by the second access circuitry. The second address is then shifted by the amount of an integer of picture frames in accordance with the result of the comparison either at the moment when the first access circuitry is granted access to the memory or when access of the first access circuitry to the memory is stopped.
