Abstract
A phase tracking network for correcting an undesirable first phase angle of a first signal, includes an error calculating circuit responsive to partial response data signals to provide a phase error signal. Filter means adapted to be coupled to the error calculating circuit is responsive to the linear and nonlinear characteristics of the phase error signal to provide a second phase angle in a second signal. A phase correction network coupled between the filter means and the error calculating circuit is responsive to the second phase angle in the second signal to correct the first phase angle in the first signal.
