  • Strong and weak signal preamplification system
    Patent number: 4416023
    Abstract: In a television receiver system having an antenna and a preamplifier, the antenna is chosen to receive signals from distant stations. Weak signals are amplified and applied to the receiver through an adjustable attentuator. Strong signals from near stations are held to a maximum level before amplification and before application to the receiver through the adjustable attenuator. Manual adjustment of the attenuator enables the viewer to adjust the signal to optimize the television picture.
