ABSTRACT:
An automatic gain control (AGC) circuit has a first filter to which a received signal is applied, followed by a variable level adjusting circuit, for producing an automatic gain controlled signal. A feedback loop set up between the input and output of the variable level adjusting circuit, contains a second filter exhibiting a narrower equivalent noise band width than that of the first filter. The second filter responds a particular signal component having a predetermined frequency spectrum and a certain duration and performs an integration operation on the particular signal component.
