Abstract Apparatus and Method for Producing a Signal-To-Noise Ratio Figure of Merit for Digitally-Encoded-Data Apparatus and method for estimating a signal-to- noise ratio figure of merit of a received digitally- encoded binary sequence. The data sequence originates from a source which transmits the data with transitions between logic states at the source occurring only at predetermined epoch time points. The apparatus includes circuitry for producing transition signals whenever a transition is detected in the received data. Circuitry for generating reference signals from the received data indicative of the predetermined epoch time points of the transmitted data are also produced. The transition and reference signals are used to produce deviation data which represent the time difference between the transitions in the received data and the epoch time points. Typically, the reference signals are used to allocate the transition signals into deviation data groupings in accordance with the time in which the transition occurs. The deviation data groupings are then characterized to produce a figure of merit value.
