Abstract (en)

[origin: DE19735752A1] The noise compression method involves feeding the data flow through a distortion correction device with coarse and fine settings and via a series level detector whose output is fed back to the distortion correction device via a controller. The data flow is sampled with a measurement period corresp. to at least twice the length of the maximum null clock length. The sample clock is sized to perform under-sampling. Three reference levels are used and a sample signal is derived from each reference level. A coarse or fine setting is selected depending on the percentage number of upper and lower threshold violations.
