Abstract:
1. A method for adjusting a signal, comprising: using an equalizer, applying at least one of a loss compensation for frequency-dependent distortion and an offset compensation for direct current offset (“DC-offset”) distortion to a signal before or after the distortion occurs to generate an output signal; using a clock signal, sampling the output signal at a sampler to generate a plurality of data values and boundary values; using a controller, monitoring the sampled values for a first set of data patterns; using the controller, detecting in the sampled values one of the data patterns in the first set of data patterns; using the controller, adjusting at least one of the loss compensation and the offset compensation applied to the signal based on one or more of the sampled data values and boundary values associated with the detected data pattern in the first set of data patterns; after adjusting at least one of the loss compensation and the offset compensation, monitoring the sampled values for a second set of data patterns using the controller; using the controller, detecting in the sampled values one of the data patterns in the second set of data patterns; and using the controller, adjusting at least one of the loss compensation and the offset compensation applied to the signal based on one or more of the sampled data values and boundary values associated with the detected data pattern in the second set of data patterns.
