Cyclic data signal averaging system and method for use in video display systems

An apparatus for reducing periodic intensity variation in a video image, comprising:

• a plurality of input signals, each input signal in the plurality of input signals representing a column of video image data;
• a first cross-point switch receiving the plurality of input signals, the first cross-point switch repeatedly sequentially shifting each input signal through an analog circuit portion, the analog circuit portion including sets of components each having an digital to analog converter and an operational amplifier;
• and
• a second cross-point switch receiving the amplified output of the analog circuit portion, the second cross-point switch separating each amplified output to produce an output signal, such that each output signal has an amplitude that matches a corresponding input signal.

An apparatus for reducing periodic intensity variation in a video image, comprising:

• means for rotating a plurality of input signals to a video display circuit so that each input signal in the plurality of input signals is repeatedly sequentially shifted;
• means for converting each input signal from digital to analog and amplifying each signal;
• and
• means for separating each amplified signal to produce a plurality of output signals, each output signal in the plurality of output signals having an amplitude that matches a corresponding input signal.

A method of reducing periodic intensity variation in a video image, comprising:

• providing a plurality of analog input signals to a video display system;
• rotating the plurality of analog input signals so that each input signal is repeatedly sequentially shifted to produce a plurality of output signals;
• and
• demultiplexing and amplifying the plurality of output signals,
• wherein each output signal in the plurality of output signals has an amplitude matching a corresponding input signal.
