  • Patent number: 4001504
    Abstract: In a digital data transmission system, a unique character marks the beginning of a data message. The speed at which that character is transmitted is sensed and the receiver speed set accordingly through the provision of a counter to count successive one-state bits in a constant speed dibit carrier for the unique character. A decoder responds to particular dibit counts to set speed latches corresponding to the speed at which the character was transmitted.
