Default constructing an astable multivibrator with logic gate

i got an hw about astable multivibrtor with logic gate and got no schemes nor diagrams about this subject.i need help about building this circuit, materials etc. i found something about astable multivibrators but non with logic gate. can someone firstly tell me what is the difference between logic gated and non-logic gated multivibrators ?

I'd bet if you look for "square-wave oscillators" you'll find a bunch of them. Most use inverters like 7404's with an R-C network giving enough phase shift to make an oscillator. That's your logic gate kind.

You can also make oscillators out of op amps or individual transistors. Look for oscillators instead of multivibrators.

Thanks a lot for your help , i should ask that to my teacher and as you said i searched about square-wave osciliators and probably thats what i'm looking for thanks again for your help.i'll write back if thats true or not.
