4.5 Data Slicer Threshold Generation
The threshold of the data slicer, especially for a coding scheme without DC-con-
tent, can be generated using an external R-C integrator as shown in Figure 4-
5. The time constant T
the longest period of no signal change T
culation of the time constant T
ANV1.1“, chapter „4.11 Data Slicer“. In order to keep distortion low, the mini-
mum value for R1 is 20k Ω .
Figure 4-5
In case of ASK operation another possibility for threshold generation is to use
the peak detector in connection 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.
