    摘要: A video graphics array color signal generator is provided. The signal generator includes an FPGA (field program gate array) device (1), a PROM (programmable read only memory) (2), a PLL (phase locked loop) circuit (3), a D/A (digital/analog) convertor (4) connected with the FPGA device, a VGA (video graphics array) interface (5), a pixel clock generator (6) which generates pixel clocks continuously at a frequency, and a keyboard (7) which provides operating buttons for users.
