Hello,
I am looking to built an op-amp based automatic gain control for low frequency sine wave signals (1Khz-10Khz). The circuit must detect varying amplitudes and stabilize them to a set value (say 10Vpp). Example: Input = 1Vpp sine wave of 1Khz, Output = must be 1Khz sine wave at 10Vpp. This circuit needs to manage it without user input. Please help, I have looked through all the books in my library but cannot find an answer.
