Patent number: 4628345Abstract: An analog digital conversion is provided for two color difference signals, for example for a recording according to a timeplex method. The color difference signals are adjusted in their amplitude at the input of the analog digital converter such that the modulation range of the analog digital converter is always fully used independent of the original amplitude of the color difference signal. The amplitude is restored back to its original value after a digital to analog reconversion. This results in an improvement of the signal to noise ratio during the transmission. The amplification provided to the various signals can be controlled by comparator circuits comparing the signal level with a reference signal.Type: GrantFiled: September 14, 1984Date of Patent: December 9, 1986Assignee: Deutsche Thomson-Brandt GmbHInventors: Erich Geiger, Bernhard Otto, Jurgen Kaaden
