what is metastabilty state ? is it analog or digital?
 

Dear Bhavs,
Metastability is a state between 0 and 1.
Its a analog.
 

hi

can u tell me hw u r saying metastability is analog...
 

nothing in this world is such as digital everything is analog.we consider it as digital.
like the clock waveform which we use in digital systems is actually an analog clock.
i think people with diferent views put in different ways.

Metastability is a state where your flip flop output is neither in a 1 or 0 state. It is in a transitioning state and could go into 1 or 0, depending on the flop characteristics. This uncertainty can be due to a violation in the flops setup or hold time.

It can be considered as an analog state.

When ever there is setup and hold time violations in any flip-flop, Flip-flop enters a state, where its output is unpredictable, this state is know as metastable state (quasi stable state), at the end of metastable state, Flip-Flop settles down to either '1' or '0'. This whole prcoess is know as metastability
