Abstract:
A signal processor for use with a standard non-interlaced computer monitor comprising:at least one video input for receiving a video input signal in at least one of an analog format and a digital format;means for generating a resized non-interlaced video image based on the video input signal;a dedicated digital processor and associated RAM, ROM and control logic;a dual RAM bank in communication with the digital processor for storing information representing at least one of a graphic video waveform and a vector diagram;first and second A/D converters;a waveform sweep generator;a vertical lookup table and a horizontal lookup table both having outputs in communication with the dual RAM bank;a two to one multiplexer having an output coupled to the horizontal lookup table, the first A/D converter having an output in communication with an input of the vertical lookup table, the second A/D converter having an output in communication with a first input of the 2 to 1 multiplexer, the waveform sweep generator having an output in communication with a second input of the 2 to 1 multiplexer, wherein the first A/D converter is operable to digitize information representing a y-axis of at least one of the graphic video waveform and vector diagram, and the second A/D converter is operable to digitize information representing an x-axis of at least one of the graphic video waveform and vector diagram, the dual RAM bank being operable to store the digitized information representing the y-axis and x-axis graphic video waveform and vector diagram, the digital processor being operable to control the outputting of information stored in the dual RAM bank for display of the graphic video waveform and vector diagram;means for generating an output for simultaneously displaying at least two of the resized non-interlaced video image, graphic video waveform and vector diagram in progressive scan format, each in a portion of the standard non-interlaced computer monitor.
