ABSTRACT:
Received data information is converted into digital data by sampling the data information and making a determination of the digital state for each bit. It is important that the clock which controls the time at which each data decision is made occurs at an optimal time, i.e. at the maximum signal to noise ratio of the received data information. This invention provides an improved clock control apparatus in which the clock timing is updated only upon receipt of one of a predetermined set of data sequences to enhance optimal timing.
