Attenuation and spread caused by a lossy transmission channel to a pulse signal waveform, having a peak h0 at t0 and sampled at Unit Intervals (UI), is measured and compensated for by dynamically adjusting the slicing threshold (21) and the timing at which the peak is sampled (22) according to the size of the eye diagram (55) at whose corners (51-54) extra test samples are taken. The data slicing level 21 and time 22 together define a data slicing point 20. Points 51 & 52 determine the slicing threshold and offset, while points 53 & 54 determine the clock recovery period and offset. |
