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