摘要： A transferred data recovery apparatus capable of recovering transferred data from a transferred data signal has a first comparator for comparing transferred data signal with a reference level R to output binary-quantized data signal representing whether or not the transferred data signal is higher than the reference level R. A sample and hold circuit is driven by a clock signal and samples the binary quantized data signal each clock period to output sampled digital data to an averaging circuit. The averaging circuit sequentially averages a predetermined number of the sampled digital data each clock period to produced averaged outputs. A second comparing circuit digitally compares the averaged outputs against an upper reference level and a lower reference level dependent upon the direction of change to produce a recovered data output. The recovered data output goes low when the averaged output goes lower than the lower reference level and goes high when the averaged output goes above the upper reference level.
