| 中文摘要:为适应不同应用场景下对多种信号类型和特性的需求改变，设计一种基于可编程逻辑器件的多功能信号源，以解决通信信号输出过程存在偏差问题。基于可编程逻辑器件进行多功能信号源的电路排布，采用巴特沃斯低通滤波器对信号噪声进行处理，确定波形优化指标，利用数字频率合成技术进行信号波形优化，设计顶层逻辑模块布局。对设计的多功能信号源进行性能测试，结果表明：在改变载波频率和调制度的情况下，设计的多功能信号源在传输过程中输出的信号频谱和解调波形的偏置精度，均优于传统的信号源。 |

| Abstract:The changing requirements for different signal types and characteristics in different application scenarios result in deviations in the communication signal output process. Therefore, a multifunctional signal source based on programmable logic devices is designed. The circuit layout of a multifunctional signal source is based on programmable logic devices, and the signal noise is processed using a Butterworth low-pass filter to determine waveform optimization indicators. The signal waveform is optimized using digital frequency synthesis technology, and the top-level logic module layout is designed. The performance test of the designed multifunctional signal source shows that the bias accuracy of the signal spectrum and demodulation waveform output by the designed multifunctional signal source during transmission is better than that of traditional signal sources when changing the carrier frequency and modulation level. |
