Abstract
In a circuit arrangement for the correction of falsified sample values in a PCM transmission system, which arrangement includes an interpolation member connected for deriving a corrected value to replace each falsified value by interpolation between sample values preceding and succeeding the falsified value in time, the interpolation member is provided with components connected for deriving each corrected value by effecting a weighted combination of the sample value appearing at the output of the interpolation member and preceding the falsified value in time and the next unfalsified sample value succeeding the falsified value in time in order to perform an at least approximately linear interpolation between sample values which are thus combined.
