Minimum Pulse Width Sensed by the GPIO of the STM32?

[Md_Aslam]

What should be the minimum pulse width of the signal which can be detected by the GPIO pin of the STM32 and on which factor this detection depends upon?

If you are talking about minimum pulse length detected by EXTI, it's given in the datasheet to your STM32, for example:
