ABSTRACT:
A sample timing recovery arrangement for synchronous amplitude and phase modulated digital data transmission systems correlates present and delayed samples of received digital data signals to obtain a spectral line at the sampling rate using digital techniques. Conventional methods of timing recovery generally perform analog operations on the envelope of a received data signal.
