In this paper, we propose the design and implementation mechanism for different digital modulators such as Quadrature Amplitude QAM-16 modulators based on the use of Quadrature Direct Digital Frequency Synthesizer (QDDFS) using Cyclone II EP2C20F484C7 FPGA from ALTERA placed on education and development board DE-1 with the following parameters:-Clock frequency : FCLK=50MHz .-Modulation type of signal is : QAM-16 .-Frequency range : (0.011 Hz…10 MHz) .-Frequency Resolution : (0.011 Hz) .-Signal amplitude (5V) .-Data frequency : 1KHz .-Digital designs allow the slides to modify and design development for results and better through reprogramming, depending on the user's desire.
