Introduction to Voltage Amplifiers (Amplifiers #1)

What's the difference between a good amplifier and a bad amplifier? Why would you need an amplifier with a gain of 1 for example? Let's see why you really need amplifiers in circuits. What is an ideal amplifier, and what is the gain, input impedance, and output impedance of a good amplifier?

Hi Aaron, I just wanted to say that I'm studying electrical engineering and I have to make a fully functional amplifier with an equalizer, mixer and volume indicator. These video's are very helpful. Keep doing what you are doing!

I am just trying to get an amplifier which is hard enough.
Also trying for the lowest possible noisefloor, I just want it quiet. Or as quiet as possible at least.

Great work.

Excellent summary

I made an amplifier with 2 mosfet but it did not work as i tought. Ac signal shifted up and became dc signal. Still works, i can hear but it has an end point where stops working. How is it possible to change just amplitude of ac signal and not move it up?
