Description
Summary:	FPGA based implementations of digital modulation techniques are carried out in this paper. These are useful for in education streams in a digital communication subject. The user can manipulate the input carrier signal and the modulating signal. These digital modulators were created in Xilinx System generator and were later implemented into Nexys 2 Spartan 3E FPGA board. The advantages are the minimum number of digital blocks used the ability to control input frequencies and are compatible with the Xilinx's FPGA boards. The experimental results such as utilization reports, junction temperature and total on-chip power are obtained in Xilinx ISE 14.7 design suite. The waveforms generated are viewed using scope block of Simulink in the system generator.
