9.3.2 Calculations

In this section a collection of formulas is given to ease the conversion of pulse train parameters.

Note

All formulas below are given for rectangular pulses.

pulse duration

pulse period

pulse peak power

Peak

pulse average power

Repetition rate is related to pulse period:

Duty cycle is the ratio of pulse duration to pulse period:

Pulse average power:

Pulse peak power:

Energy: The measurement unit of energy is J (Joule) - 1J is the energy that is necessary to

provide the power of 1 W during 1s. It can be calculated from the peak power of the pulse and

the pulse duration:
