Abstract
A system in which automatic gain control is not applied to modify an incoming carrier signal over the first 40 dB of signal level, employs an AGC system in which a further signal is generated for further modification of the modified carrier signal to obtain the original carrier signal modified by a linear logarithmic response to the AGC signal over the entire signal range of the apparatus. In addition, automatic gain control signals derived from both an envelope AM detector and a synchronous AM detector are added together whereby a continuous AGC signal is generated regardless of the source of the signal.
