I have a question about Harmonic Distortion.
I designed a three stage bjt amplifier for a class project and to simplify my calculations I grounded the emitter on the second stage. This had the expected affect of killing my gain on the first stage and I accounted for that. However, I also thought that doing so would add a lot of harmonic distortion. When I simulated it and constructed it in lab I ended up with a THD of about 0.5%. I can't think of any reason why this is so low. I was wondering if you had any suggestions on what I could investigate to figure out what is keeping the harmonic distortion down.
