Pulse width (tp) of Mono-stable multi-vibrator= 1.1 RC.
Pulse width (tp) of Non-triggerable Mono-stable multi-vibrator= 0.69 RC.
Pulse width (tp) of Re-triggerable Mono-stable multi-vibrator= 0.32 RC.
Pulse width (tp) of Non-triggerable Mono-stable multi-vibrator= 0.69 RC.
Pulse width (tp) of Re-triggerable Mono-stable multi-vibrator= 0.32 RC.
