3.7.1
The high time of data is used to measure the frequency of the data signal. For Manchester coding
either the data frequency or half of the data frequency have to be detected corresponding to one
high time or twice the high time of data signal.
A time period of 3*2*T is necessary to decide about valid or invalid data.
Figure 3-33
Example to calculate the thresholds for a given data rate:
- Data signal manchester coded
- Data Rate: 2kbit//s
- f
Then the period equals to
respectively the high time is 0,25ms.
We set the thresholds to +-10% and get: T1= 0,225ms and T2= 0,275ms
The thresholds TH1 and TH2 are calculated with following formulas
