monostable and astable...

[ar3s]

hi everybody, i'm new in this forum and also newbie in electronics.    i want to ask something very basic perhaps, how do monostable and astable flip-flop REALLY work? i know that it has something to do with the capacitor but i just don't get it??  ???  can anybody explain them along with the circuit diagram? thanks before...

Flip flops or multivibrators are used as memory units and for generating clock waveforms.
It is only the capacitor arrangement wrt the resistor which makes it mono ,bi or astable .
But each has 2 states a 1 and a 0.
In one case the capacitors are  charged and does not allow state to change(bistable) ;D
