ABSTRACT:
A device for digital acquisition, storage and processing of time-dependent data signals, especially for the accumulation of interferograms delivered by spin resonance and infrared spectrometers, comprises an A/D converter; a main memory having random access; a disk storage; a data channel connecting the A/D converter with the main memory which data channel contains a pointer register and a word counter and carries out the direct transfer of words delivered by the A/D converter to that area of the main memory indicated by the contents of the pointer register, the number of words being defined by the contents of the word counter; and a central unit which loads the pointer register and the word counter at the beginning of each measurement period and activates the transfer of word blocks from the main memory to the disk storage and vice versa. In such a device, a significant reduction of the processing time required by the transition from one word block to the following word block is achieved by providing the data channel 3 with an addressing register 15 assigned to the pointer register 14 with a block length register 17 assigned to the word counter 16 and with a block counter 18, the address register, the block length register and the block counter 18 being loaded at the beginning of a measurement procedure from the central unit 7, whereas the pointer register 14 and the word counter16 are always loaded before starting the accumulation of each word block by transferring the data from the address or block length register 15, 17, until the number of word blocks determined by the contents of the block counter has been accumulated.
