Abstract

PURPOSE: To obtain the correction signal through the arithmetic operation of a series of signals free from erros of not less than 4 reversed in terms of time in case the code error occurs to the reproduction signal, thus ensuring the correction effect even to the sine wave signal of a high frequency.
CONSTITUTION: Analog charge transfer element 1 has the tap with every step, and the data is transferred by a step and with the clock equal to the sampling frequency. Accordingly, 9 data are stored based on the time sequence and via the signal sent from D/A converter J. The correction signal is delivered to point (b) from 8 data obtained by excluding the middle one among the 9 data and through the addition and subtraction carried out via resistors 4W12 plus operational amplifier 2. Now in case the code error occurs, the error corrector generates the correction signal via the arithmetic operation of the signal free from errors of not less than 4 reversed in terms of time and after the D/A conversion. And then analog switch 3 is switched from (a) to (b) to deliver the correction signal. In such way, the correction effect can be ensured even to the sine wave signal of a high frequency.
