Methods and systems for mitigating latency in a data detector feedback loop are included. For example, a method for reducing latency in an error corrected data retrieval system is included. The method includes performing an analog to digital conversion at a sampling instant to create a digital sample, and performing a data detection on the digital sample to create a detected output. The detected output is compared with the digital sample to determine a phase error. During an interim period, the digital sample is adjusted to reflect the phase error to create an adjusted digital sample. After the interim period, the sampling instant is adjusted to reflect the phase error.

A ceramic composite is able to whithstand temperatures in excess of 2200 F on a repeated basis without cracking due to thermal shock. The composite has a web of reinforcement fibers; and a matrix that substantially the web after the firing step. The matrix is formed around the web by impregnating the web with a sol containing alumina and, in some cases, rare earth oxides, and firing the composite after the impregnation. The web may be a three-dimensional orthogonal weave of the reinforcement fibers, where the fibers are a transitional phase alumina. The composite is essentially free of Group I and Group II metals and transition metal oxides. The composite may be used as a refractory brick or lining and may also be used as an insulatingmaterial due to its chemically non-reactive nature.

A digital level control circuit, such as an Automatic Gain Control, includes a plurality of digitally selectable signal levels with transitions between levels gradually varied to avoid signal output level discontinuities. An up / down counter may be used to incrementally stepwise transition an output signal between the digitally selectable output levels. Stepwise application of a control signal to the appropriate switching elements (e.g., FETs) forming an attenuator circuit may be implemented to moderate a switching time of the switching elements to provide a more gradual transition between element operating states. A deglitch circuit may be employed to latch the switching elements to achieve the desired state at the end of a desired switching transition period.
