Would you guys please tell me how to measure in I/o impedences of a CE amplifier. I found out about a way how to do it using a potentiometer. But since I dont have a potentiometer, is there an alternative way to it? If i just use the DMM across the input or ourput and tge ground will I get the right value of resistance. how about measuring the internal resistance of the frequency generator, How can I do that? sorry for asking these very basic questions!
