  • Patent number: 4479230
    Abstract: A process and apparatus for the synchronization on reception of a signal provided with a synchronization pattern. The process consists of retaining the synchronization setting until it can be readjusted on a periodically appearing potential synchronization pattern, optionally in the absence of a reference synchronization pattern corresponding to a previously acquired synchronization. The apparatus has a potential time base loaded to a given count during the presence of a potential synchronization pattern and a reference time base looped on itself and producing a synchronization signal when it reaches a given count. If a potential synchronization pattern is present in an iterative manner, a logic circuit produces a signal causing the synchronization change by loading the reference time base with the potential time base.

  • Patent number: 4459701
    Abstract: A process is provided for synchronizing at reception digital signals transmitted in packages which consists in generating the signals of a first window of given width at intervals corresponding to the timing of the on-line packages, in searching by detection for at least one transition in the signals received during the duration of each window, in modifying the interval between the beginning of a window signal and the beginning of the following signal in the case where the transitions detected do not correspond to a given criterion and in maintaining said interval equal to said on-line package timing and producing a synchronization signal fed to a package reading device in the opposite case. The device of the invention comprises a dividing counter which is reset by the transitions detected in the window so that the interval between the successive windows is modified until the synchronization is acquired, that is to say that the end of the window is located at the level of the synchronization transition T.sub.

  • Patent number: 4264884
    Abstract: Charge transfer filtering device which comprises a recursive filter and a non-recursive filter. The two filters on separate semiconductor substrates have charge injection means 12, 10 receiving the input signal E for the non-recursive filter 2 and the output signal S, previously phase-displaced by 180.degree. by means 9, for the recursive filter 1. Means 15, 16, common to both filters, ensure the reading and summation of the charge quantities weighted by means P and 14 and then the supply of the output signal S.
