Abstract
An analog-to-digital signal conversion system includes two analog-to-digital converters having equal inherent frequencies. The analog-to-digital converters share common input channels, and the output of each analog-to-digital converter is directed to a multiplexer that is arranged on a programmable logic device. The converters alternate in the sampling of analog signals, thus delivering digital signals to the multiplexer at a higher speed than either analog-to-digital converter could do on an individual basis. The multiplexer delivers the digital signals to slots of a memory mailbox, where the slots correspond to the input channels of each converter.
