ABSTRACT:
The invention is an automatic gain control (AGC) sampling structure in which a conventional closed loop AGC circuit detects a received level and generates a direct current voltage for controlling an amplification stage. This direct current voltage is sampled and the optimum control voltage is selected from the samples based on the technique of ordered statistics. The conventional AGC control loop is interrupted and the selected control voltage is provided to the amplification stage.
