Period: Time to take for the signal cycle to complete in the waveform
Frequency: Reciprocal of the period of the first cycle in the waveform
Rise Time: Time taken from lower threshold to upper threshold
Fall Time: Time taken from upper threshold to lower threshold
+Duty Cycle: Positive Duty Cycle = (Positive Pulse Width)/Period x 100%,Measured of
the first cycle in the waveform
-Duty Cycle: Negative Duty Cycle = (Negative Pulse Width)/Period x 100%, Measuredof
the first cycle in the waveform
+Pulse Width: Measured of the first positive pulse in the waveform. The time between the
50% amplitude points
-Pulse Width: Measured of the first negative pulse in the waveform. The time between the
50% amplitude points
