Delay time (td): the time required from 50% rising of OUTPUT2 to the decrease to 90% of the
maximum value of LINE2
Falling time (tf): the time taken for the amplitude of LINE2 to decrease from 90% to 10% of the
maximum value
Storage time (ts): the time required from 50% falling of OUTPUT2 to the rise to 10% of the maximum
value of LINE2
Rising time (tr): the time for the response of LINE2 to rise from 10% to 90% of its final value
