  • SYSTEM AND METHOD FOR SPLIT AUTOMATIC GAIN CONTROL
    Publication number: 20080152170
    Abstract: A system and method for automatically controlling gain in a signal chain are presented. A first signal is processed to produce a processed signal. A gain is adjustably applied to the processed signal using an automatic gain control (AGC) mechanism. A resulting signal is produced. The gain is adjusted based on the first signal. As such, even when a desired signal is not substantially present in the first signal, gain is not excessively applied to the processed signal.

  • Receiver for audible alarm
    Patent number: 4617555
    Abstract: A receiver to detect the audio tone emitted by an activated smoke alarm. The receiver employs an electret condenser microphone to monitor ambient sound. The output of the microphone is applied to an active band-pass filter and then to a PLL tone decoder. The PLL is tunable to provide maximum sensitivity to the frequency of the tone. The microphone is the gain controllable element in an AGC system that acts to keep received signals at a constant level. This insures that all devices operate linearly.
