Abstract
A system for processing Sigma-Delta CODEC. The system includes modulation/demodulation device, Bus, a software-controlled digital signal processor, and Virtual Device Driver (Vxd). Providing high speeds data for operational analysis, transmission and access by the processing ability of CPU and interrelated aided circuits. The present invention provides various digital signal processes that the Virtual Device Driver (Vxd) mates with the processing ability of CPU without replacing by other hardware device (such as the sound card).
