Hi sirs/madams,
I have a hard time setting my highest freq for my Class A amplifier (CE configuration), i learned that Couplings and Bypass are used to set the lowest freq (correct me if im wrong - i learned this through internet ). And i dont have any idea how to set my highest freq and i dont even know what i should do to control it. Can you guide me somehow? I would like to have 300Hz to 30kHz range.

 

Hi,

You mean like a low pass filter?

In general, an increase in a parallel capacitance lowers the high end response while an increase in a series capacitance raises the low end response.

 

@MrAl Yes sir. I just found out that through internet that in a class A amplifier ( BJT Transistor), i can set my lower cutoff freq through the Couplings and bypass. It was stated that Cc and Cb act as a high pass filter, is that correct sir?

 

Hello,

You already have a thread for your amplifier:
Amp FAIL!
