01:13:38

Sup, tried to make a amplifier with gain of 10 and a filter at 1000Hz and 14000Hz probably there are many mistakes in there, comments are open for suggestions please leave some comments for adjustments thx a lot. Btw this is my first week lab homework for my uni.

Why the 500mH inductor at the output? Inductors are never used in this manner, especially 500mH. It's such a high value!

Hey thx for your comment i tried to make RL low pass filter there but as you said it has a such high value i changed it with RC low pass filter.

Use an active version. Otherwise, you could optimise the amp to give an LF rollof just by changing the input capacitor value. But that increases the THD.
