What happen when downloading the previous stage?

thank you guru

from what you said, if the o/p impedance of the first stage = 9K
and the i/p impedance of the next stage = 1k
and the signal is 1V
only (1/10) of that signal reach to the next stage
that is 0.1 volt.

If so, the word dowenload be inappropriate because I understand that the characteristics of the first stage change!

Hi Walid,
Yes, the 1V signal is attenuated to only 0.1V.

I don't say downloaded. I say the signal is loaded down.
When you put too much load on a donkey (or a camel) then it goes slower or it stops because it is loaded down.

Overloaded would be a better word but it sounds bad. An attenuator is not always bad, sometimes it is wanted.
