How to understand phase in the simplest way?

[bicave]

We need phase margin of system greater than 60 degree for stability.

How to understand phase in simplest way? look for the performance of a circuit how to know how much phase it need. Any one has intuitive understanding.

Thanks

Re: how understand phase

Phase margin is a measure of stability your circuit. If phase margin not enought great, you will have oscillatory process on unit step.
