摘要 :本系统由FPGA、单片机控制模块、键盘、LCD液晶显示屏、DAC输出电路和末级放大电路构成。仅用单片FPGA就实现了直接数字频率合成技术(DDS),产生稳幅正弦波,并在数字域实现了AM、FM、ASK、PSK等四类调制信号。调制信号既可由用户输入参数由FPGA内部生成,也可以从外部输入。整个系统结构紧凑,电路简单,功能强大,可扩展性强。
Abstrat: This system is composed by FPGA, MCU controller, keyboard, LCD, DAC and amplifier modules. The DDS, Direct Digital Synthesizer, which is implemented by a unique FPGA IC, can provide the stable sine signal with digital AM, FM, ASK, PSK modulation. The modulation signal can be provided NOT only by FPGA, which will receive parameters from user, but also from external input. This system features in compact module, simple circuit, powerful functions and flexible expansion.
