Abstract
Disclosed is a high-frequency boost circuitry for use with a computer management system. Detection circuitry at the receiving end of a video signal measures the amplitudes of various frequency components of the video signal. If the amplitudes of the high-frequency components of the video signal are substantially lower than the amplitudes of the low frequency components of the video signal, the detection circuitry sends the amplitude information to analysis circuitry located at the transmitting end of the video signal. The analysis circuitry utilizes this information to determine the appropriate level of amplification needed for the video signal. This results in improved signal to noise ratio at the receiver in the computer management system.
