Abstract: A data receiver has a digital filter which is adaptively tuned to the instantaneous bit-rate of a received noisy digital signal so as to provide an optimum transfer function despite irregularities in the received signal. A timing signal which reflects the true rate of the received signal adaptively tunes the filter, and sets the bit-rate at which the filter output is digitized. The data receiver output is a digital signal which is a reconstruction of the information content of the received digital signal with low probability of error.
