Abstract :
New types of discrete-time automatic gain control (AGC) circuits are proposed. The AGCs are based on iterative processes, and both feedforward and feedback structures are considered for two different signal energy detectors: mean absolute deviation (MAD) and root mean square (RMS). The different algorithms were implemented on a digital signal processor, and experimental results are presented
