Abstract
The development of a terminal for voice and data transmision based on the TMS 32010 one-chip microprocessor is described. Simple solutions are provided for the digital implementations of the filters, compandor, equalizer and modems. A new FFT-based method for obtaining the equalizer coeficients is developed with excelent results. A DPSK 1200 bps data modem is also designed to make possible silmultaneous transmision of voice and data over a 4 KHz channel.
