Abstract
Aspects of the disclosure provide a signal processing circuit that includes a signal processing circuit includes a processing path configured to process an electrical signal to produce input data samples, and a feed-forward correction module configured to delay the input data samples to produce delayed data samples, to apply the delayed data samples to a timing loop during periods when a profile variation of the data samples is not detected, and to apply the input data sample to the timing loop during periods when a profile variation of the data samples is detected.
Claims20
A signal processing circuit, comprising:
- a processing path configured to process an electrical signal to produce input data samples;
- and
- a feed-forward correction module configured to delay the input data samples to produce delayed data samples, and to apply the delayed data samples to a timing loop during periods when a profile variation of the data samples is detected.
A signal processing method, comprising:
- receiving input data samples;
- detecting whether or not a profile variation of the input data samples is occurring;
- delaying the received data samples to produce delayed data samples;
- and
- applying the delayed data samples to a timing loop during periods when a profile variation of the data samples is detected.
