A duty cycle is the percentage of the waveform that occurs above the zero axis. The duty cycle of a square wave is always 50%, or 1/2. Because the duty cycle is 1/2, every second harmonic is not present.

What is the formula for duty cycle?
Period = 1/Frequency (2) Period= T on +T off (3) Duty Cycle= T on / (T on +T off ) * 100 (percentage) (4)
What is a 50% duty cycle square wave?
The ratio of the high period to the total period of a pulse wave is called the duty cycle. A true square wave has a 50% duty cycle (equal high and low periods). Square waves are often encountered in electronics and signal processing, particularly digital electronics and digital signal processing.
What is the formula for a square wave?
the square wave and f is its frequency, which are related by the equation f = 1/T.
What is the duty cycle D of a square wave generator?
For a rectangular waveform, the ratio of the pulse duration (tµ) to the period T is referred to as the duty cycle (d) of the waveform. A square wave is a rectangular waveform with d = 0.5 or 50% duty cycle.
