Abstract:
A data slicer for squaring-up a digital input signal recovered by a receiver demodulator, the data slicer comprising:a comparator containing at least a first input terminal to which the input signal is applied, and a second input terminal to which a reference level is applied; a filter to which the input signal is applied, the output of which constitutes the reference level and is applied to the second terminal of the comparator; a signal level measurement circuit for measuring the reference level, the input of which is connected to the second terminal of the comparator; a switch with output connected to the second terminal of the comparator; a signal generator having an output connected to the switch input; a controller, which controller is connected to the signal level measurement circuit output, the signal generator, and the switch; whereby the output of the comparator is the squared-up digital signal, and the controller can measure and specify the reference level.
