I know the transfer function of feedback system, when loop gain become negative 1, denominator becomes zero, and the gain shoots up to infinity. All nice and simple on paper but I need a intuitive explanation for this thing (i.e., Barkhausen criterion ).
If any control, electronics engineers or hobbyist help to grasp the concept.
Thanks in advance 🙂

Because you turn negative feedback into positive feedback. If the gain is *precisely* 1, then the feedback system will be in a metastable state.

If you’re riding your bike and a cat jumps in front of you, you jam the handlebars to one side. Since the bike doesn’t move immediately, you jam it too far and you fall over.
