Is it possible to generate different PWM Signals for same duty cycles(e.g. 50%)?
You can change the waveform and period, duty cycle is "the fraction of one period in which a signal or system is active".

As long as you have a period, you can determine a duty cycle.

One different type of PWM I have encountered is nonconsecutive PWM.
