A method and transverse - equalizer for the automatic adaptive equalizing of more level of strength digital signals

摘要

The equaliser continuously carries out also an amplitude adjustment. A unit corrects the phase in consecutive error signal cycles between the read-out and quantised signal. One cycle comprises the signal passage through a signal reading device, a quantising unit for the read-out signal, circuits evaluating the error between the read-out and quantised signal, and the phase changing unit, the cycles are continued until the error signal gradient is eliminated. A unit varies the coefficients between the read-out and quantised signal. A cycle comprises the signal passage through an equaliser, an amplifier, a reading device, the quantising unit, circuits evaluating the errors, and the coefficient varying device. The cycles are carried out unitl the error signal gradient is eliminated. The signal amplitude is adjusted by a third device.
