Wireless Components
4.5 Data Slicer Threshold Generation
The threshold of the data slicer can be generated using an external R-C inte-
grator as shown in Figure 4-5. 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 .
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.
