    Abstract: An error correcting apparatus including a syndrome calculator for calculating syndromes from input data added with an error correction code, a data memory which is connected in parallel with the syndrome calculator for storing the input data, a syndrome memory to store syndromes calculated by the syndrome calculator, and an error correction processor for executing error correction of the data in the data memory by using the syndromes stored in the syndrome memory. The error correction code is provided in both first and second directions when data is two-dimensionally arranged, and the error correction processor obtains values in which the result of an arithmetic operation for error correction in at least one of the first and second directions is added to syndromes in the other direction. An error position within the input data is detected and corrected again on the basis of the values.

    Abstract: A digital information restoring device is arranged to detect time between level transition points of a digital signal which indicates digital information by means of variations in its period, output the resultant period data, calculate an average value of at least two period data among the output period data, and compare the average value with the aforesaid period data, and restore the digital information. The digital information restoring device is, therefore, capable of restoring the digital information at a high speed without using a high-speed PLL circuit or the like. The digital information restoring device may also be arranged to perform time-axis expansion of only part of the received period data, and input the resultant period data to a computing circuit to restore the digital information.

    Abstract: A data transmission system operative to transmit data with a reduced low band frequency component includes facility for processing a predetermined quantity of information data, such as a code word, for generating error detecting-correcting data, and for dispersing the latter data in the former data. In one practice for effecting the dispersion, the system divides the information data and the error detecting-correcting data into respective groupings, and disperses the latter grouping into the former grouping. The resulting signal is transmitted.

    Abstract: In a method of driving a liquid crystal panel using one horizontal period (1H) as a reversal period, the liquid crystal panel using a TFT as a switching element for driving the panel in units of divided blocks and comprising the block division TFT's (B-TFT), a matrix circuit for driving each block in time division, and a TFT active matrix panel; each block of the B-TFT's is further divided into two half-blocks and a control signal shifted in phase between adjacent two half-blocks is applied to time-divisionally drive the liquid crystal panel at superposed timings. High intensity lines produced at the intersection of blocks due to the charge sharing effect are eliminated to thereby enable a high quality image to be produced.
