Time Parameters
RiseTime
Period: defined as the time between the middle threshold points of two
1.
consecutive, like-polarity edges.
2. Frequency: defined as the reciprocal of period.
Rise Time: the time for the signal amplitude to rise from 10% to 90%.
3.
Fall Time: the time for the signal amplitude to fall from 90% to 10%.
4.
+ Width: the time difference between the 50% threshold of a rising edge to the
5.
50% threshold of the next falling edge.
6. - Width: the time difference between the 50% threshold of a falling edge to the
50% threshold of the next rising edge.
+ Duty: the ratio of the positive pulse width to the period.
7.
- Duty: the ratio of the negative pulse width to the period.
