Figure 10.1 Time Parameters
• Period: defined as the time between the middle threshold points of two
consecutive, like-polarity edges.
• Frequency: defined as the reciprocal of period.
• Rise Time: indicates the time for the signal amplitude to rise from the threshold
lower limit to the threshold upper limit.
• Fall Time: indicates the time for the signal amplitude to rise from the threshold
upper limit to the threshold lower limit.
• +Width: indicates the time between the threshold middle value of a rising edge
to the threshold middle value of the next falling edge.
• -Width: indicates the time between the threshold middle value of a falling edge
to the threshold middle value of the next rising edge.
• +Duty: indicates the ratio of the positive pulse width to the period.
• -Duty: indicates the ratio of the negative pulse width to the period.
• Tvmax: indicates the time that corresponds to the maximum value of the
waveform (Vmax).
• Tvmin: indicates the time that corresponds to the minimum value of the
waveform (Vmin).
The default values for threshold upper limit, threshold middle value, and threshold
low limit are 90%, 50%, and 10%, respectively.
