Why does a Transistor have a 50% duty cycle?

How can it be a perfect 50% duty cycle when the transistor is biased or not biased?

How you can get the 50% duty cycle[square wave] by just biasing the transistor?. Show me the circuit diagram

 

[D.A.(Tony)Stewart]

Complementary MOS or CMOS are better for self biasing to get 50% because the Dc gain is unity with 100% DC feedback and there is no offset if the threshold is Vcc/2.

Transistors have a DC offset or Vcb required so self biasing will work with needed negative feedback and high gain.

If it is indeed the case, that is an assumption provided,
not a natural outcome.

 

[stanleystan]

The Negative or Positive feedback changes the duty cycle of the transistor?

Without Negative Or Positive feedback the duty cycle of a transistor is 50% right?

 

[Audioguru]

Is the duty-cycle at the output of a transistor 50% when its input turns it on for only a moment each cycle? No.
Or when its input signal turns it off for only a moment each cycle? No.

Then the duty cycle of a transistor is not always 50%.
