These include fax modems. QAM is also used in highspeed cable, microwave, and satellite systems. It is a popular choice because it uses bandwidth efficiently

Shaojun Wei,Leibo Liu,Chenchen Dengcancellers to achieve full-duplex data transmission over 2-wire circuits. This technique was studied in the early 1980’s and then widely introduced in commercial products in the mid 1980’s, when the CCITT V.32 recommendation for a 9600 bps modem was approved. A few years later, the V.32bis recommend

Learning to Use the Hardware and Software Tools by Generating a Sine Wave, the PC and TMS320C30, the C30 assembler and linker, and the TI C source debugger for interfacing with the DSP board. The hardware includes the TMS320C30 floating point DSP and the Analog Interface Chip (AIC) on the Evaluation Module (EVM). These tools will be explored by generating a sine wave using three different methods.
