ABSTRACT:
There is disclosed a delay compensated automatic gain control which allows improved automatic gain control in analog and digitally implemented systems. The AGC system and technique includes a primary high speed control loop implemented after the intermediate frequency filtering and a secondary loop which controls the radio frequency gain prior to the intermediate frequency filter without affecting the overall response of the automatic gain control system. The resulting action of the two loops provides an automatic gain control for the radio frequency and intermediate frequency stages in both analog and digitally implemented systems without sacrificing speed of response or stability of the systems.
