ABSTRACT:
A data slicer follows abrupt variations in level of the detection signal. The data slicer for converting a detection signal into a digital signal in a data transmission system includes a maximum value detecting section, a minimum value detecting section, a voltage shift-down section, a voltage shift-up section, and a binary encoding circuit. The maximum value detecting section detects the maximum value of the detecting signal, while the minimum value detecting section detects the minimum value of the detecting signal. The voltage shift-down section sets a minimum value which the minimum value detecting section should take according to the output voltage of the maximum value detecting section, while the voltage shift-up section sets a maximum value which the maximum value detecting section should take according to the output voltage of the minimum value detecting section. The binary coding circuit operates to slice the detection signal according to the outputs of the voltage shift-down section and voltage shift-down section, to output serial data sliced.
