Abstract

In this paper we describe a low cost embedded system integrating all the functionalities needed for the analogical processing of radio communication transponder. We particularly put the emphasis on the optimized algorithm of tone and DTMF (dual tone multiple frequencies) detection in a DIP 8 microcontroller with only 64 bytes of RAM. We also present all the limits and the main advantages of our solution compared at other analogical solutions.
