Design of signal source based on FPGA

  • 摘要: 针对模拟信号源存在精度低、频率范围小,以及定制直接数字频率合成信号源的控制方式、置频速率等不满足系统要求的问题,设计了一种基于FPGA的信号源。该信号源基于直接数字频率合成原理,采用FPGA的模块化设计方法, 实现了频率、相位、幅值可调的正弦波、方波、三角波等波形输出。实验表明,该信号源输出波形质量好,频率分辨率高,控制灵活、方便。
    Abstract: In order to solve problems of low precision and small frequency range of analog signal sources and unability to satisfy system requirement of bespoke direct digital frequency synthesis signal sources on aspects of control mode and frequency setting, a signal source based on FPGA was designed. The source is based on direct digital frequency synthesis principle, it adopts modularization design of FPGA and can output sine wave, square wave and triangular wave with adjustable frequency, phase and amplitude. The experimental results show that the signal has perfect quality of output wave, high frequency resolution and convenient control.
