摘要：The device for restoring the continuous component of a digital signal

comprises: - a device for generating a correction signal, including a digital data decoder(9) and an arithmetic circuit for computing an error signal (20) based on the differencebetween the value of the signal entering the device and that of the decoded signal, and -a correction-application circuit for applying a correction signal to the input signal.According to the invention, the device is provided with means (18) for indefinitely

summing up the values of the successive error signals output by the arithmetic circuit forcomputing an error signal (20), the value of the signal established by these means beingsupplied to the correction-application circuit directly or via a fixed attenuator (28).Application: signal processing in a transmission system, the said signal comprising digitalsignals. It relates for example to a receiver in a MAC television system.
