Dual-band frequency-selective attenuator for automatic gain control |
摘要 |
Automatic gain control in a radio receiver is provided using a pair of saturable reactors in resonant circuits for providing variable attenuation. One resonant circuit has a frequency above the desired RF signal while the other has a resonant frequency below the desired RF signal. The resonant frequencies are symmetrically shifted about the desired frequency in response to the AGC signal.
