Abstract :FSK is an earlier modulation style used in the Information transmission, its main advantages are easier to achieve, the anti-noise and anti-fade performance better. In the low-speed data transmission, it widely applied.
This FSK modulation system is widely used in the computer network, office automation system and FSK communications. Through analysing the FSK digital modulate theory , we propose the method of how to realize FSK modulate by using waveform generator XR-2206. before the hardware electric circuit designed , I selected MAXPLUS II software to carry on the simulation to the FSK modulation . Programs with the VHDL language realizes, and has drawn up the FSK electric circuit schematic diagram and the PCB chart with Protel software
