Astable Multivibrators are a type of "free running oscillator" that have no permanent "Meta" or "Steady" state but are continuously changing from one state "LOW" to the other state "HIGH" and then back again to its original state.
This continuous switching action from "HIGH" to "LOW" and "LOW" to "HIGH" produces a continuous square wave output which has been shown in this electronics project.
The time constant for a NAND gate astable multivibrator is given by the formula,
T = 2.2RC in seconds with the output frequency given as f = 1/T.
