Hi, I am doing AGC for a radio receiver. It's been tough. I spent a whole day on it and now I have a question.
What is the best way to perform the AGC? Should it go more positive with signal or negative? I'm thinking more positive is best because of the compression in the AGC biased amplifier but if you can manage to stay out of the cutoff region, negative bias would be more effective. I am dealing with a wide range of signal strengths. Anyone have some good tips?
