Figure 55
The next figure shows the TVWIN and TSIGAP dependency.
Figure 56
TVWIN calculation for pattern without GAP time:
The entire TVWIN time is made up of the CV
the half bit after the CV. To reach all frequency and duty cycle errors, 25% of the overall
sum must be added.
TVWIN calculation with GAP time:
1) CV...number of bits containing manchester code violations
