发明名称 Method and arrangement for the analog/digital conversion of a picture signal
摘要 A method for the analog/digital conversion and an arrangement for the analog-to-digital conversion of an analog signal, particularly a picture signal, into a digital signal by at least two analog-to-digital converters which are clocked by at least two phase-shifted clock signals and whose output signals are combined to a digital picture signal by a multiplexer is disclosed. In order to achieve an individual adaptation to different characteristics of the analog-to-digital converters, each analog-to-digital converter is preceded by an automatic gain control circuit and a clamping stage, which clamps the picture signal at a given amplitude value, the analog signal being applied to the automatic gain control circuit and the clamping stage.
