Figure 10.2 Delay and Phase Parameters
1. Delay(r-r): indicates the time difference between the threshold middle values of
the rising edge of Source A and that of Source B. Negative delay indicates that the
rising edge of Source A occurred after that of Source B.
2. Delay(f-f): indicates the time difference between the threshold middle values of
the falling edge of Source A and that of Source B. Negative delay indicates that the
falling edge of Source A occurred after that of Source B.
3. Delay(r-f): indicates the time difference between the threshold middle values of
the rising edge of Source A and the falling edge of Source B. Negative delay
indicates that the rising edge of Source A occurred after the falling edge of Source
B.
4. Delay(f-r): indicates the time difference between the threshold middle values of
the falling edge of Source A and the rising edge of Source B. Negative delay
indicates that the falling edge of Source A occurred after the rising edge of Source
B.
5. Phase(r-r): indicates the phase deviation between the threshold middle values of
the rising edge of Source A and that of Source B. The phase formula is as follows:
