Delay Time
Time between any 2 events (delay) is normally measured
between the 50% amplitude points. See Figure 14.

HOW TO MEASURE FREQUENCY
Using the method described in the preceding application,
you can measure the period (time required for 1 cycle or
time for a given number of cycles) of a recurrent waveform.
The frequency of the waveform can be calculated since
frequency is the reciprocal of the time period. For example,
if the period of a recurrent waveform is accurately measured
and found to be 20 µs, the frequency is 50 kHz. If the time
for 10 cycles is 10 ms, the frequency is:
1 x 10 = 1 kHz
10 ms
To calculate the period of a known frequency:
