Abstract
An arrangement for measuring and cancelling bias distortion is designed for correcting the distortion of the binary signals which do not comprise any zero-frequency spectral components, automatically and cyclically measures said distoration (DM) by consecutive analyses of the binary data at a sampling frequency (SCK) which is a multiple of the data frequency in order to determine the sign and the quantized value of the distortion (UDC). It includes distortion cancelling means (CC) which augment the length of the binary elements selectively as a function of the sign of the distortion and proportionally to the quantized value of the said distortion and this is done until the distortion is cancelled completely.
