Hello. I would like to ask one question about AGC (automatic gain control).
I need to design the LNA with AGC for the FM receiver.
As I know, digital AGC require many control bits and switches which complicate the design, analog AGC has higher resolution than digital ways. Except this point, could you please let me know the pons and cons of analog and digital AGC?
And if I will choose analog AGC to achieve fast response, than what is the gain settling requirement of FM system, and how fast the AGC loop should achieved?
Thank you very much
