4.5 Data Slicer Threshold Generation
The threshold of the data slicer can be generated in two ways, depending on
the signal coding scheme used. In case of a signal coding scheme without DC
content such as Manchester coding the threshold can be generated using an
external R-C integrator as shown in the following . The cut-off frequency of the
R-C integrator has to be lower than the lowest frequency appearing in the data
signal. In order to keep distortion low, the minimum value for R is 20k
.

Data Slicer Threshold Generation with External R-C Integrator
Another possibility for threshold generation is to use the peak detector in con-
nection with two resistors and one capacitor as shown in the following figure.
The component values are depending on the coding scheme and the protocol
used.
