Frequency
Frequency is defined as 1/period and it used to measure the frequency of
a waveform.
Rise Time
The rise time of a signal is the time difference between the crossing of the
lower threshold and the crossing of the upper threshold for a
positive- going edge.
Fall Time
The fall time of a signal is the time difference between the crossing of the
upper threshold and the crossing of the lower threshold for a
negative- going edge.
