Is it possible to define the ergodicity of the random signal in an intuitive sense without using any statistical reference?
When a process or system in which the average, over time, of the physical quantities that describe it coincides with the average calculated over a set of possible states of the process or of the system itself.
I would use an example like the following:
-You would have the similar results after flipping 100 coins as flipping a coin 100 times.
I hope it helps.
