A novel microprocessor based data communication system
A.R. Saha, B.C. Mazumder · 2003
A novel method of economic transmission of parallel data over a pair of wires is described. The n-bit digital word X is encoded into a pulse of duration tau (X), where f(X), the reciprocal of tau (X) is proportional to the magnitude of X. At the receiver end, information is retrieved by converting f(X) back to X by a successive approximation logic f-to-D converter technique. Appropriate protocols have been formulated for smooth flow of data. Algorithms for transmission, reception, and protocols are implemented by developing software programs for the complete system using 8085 microprocessors.>
