Latest Patents

Nobuyoshi Ukaji holds a patent for an Automatic Gain Control (AGC) circuit. This invention features a control section with two operation modes. The first mode is designed to maintain the amplitude of the sync signal at a constant value by controlling the gain of a variable gain amplifier. The second mode prevents the gain from increasing when the amplitude of the sync signal is below a predetermined reference value. This innovative approach allows for a reduction in gain only when the amplitude of the video signal exceeds a second reference value. The switching between modes is based on the amplitude of the sync signal and video signal, ensuring optimal performance in various conditions.
