摘要
波形发生器是信号处理领域中必不可少的设备。这里,介绍了基于FPGA的模拟电路中阶梯波、阶梯波等常用渐变信号的波形实现方法,并详细地阐述了其相应硬件电路的工作原理。同时,对波形的实际输出结果进行了观测。通过实验证明,这些波形清晰,可以实时调节,且电路实现简单、成本低。
The wave-form generator is the essential equipment in the signal processing domain. This paper introduces one realization method about the wave-form of the commonly used signal in analogous circuit based on FPGA, ladder Wave and saw-tooth wave, for example. And it detailedly expatiates the principle of work of the corresponding hardware circuit. At the same time, it has also carried on the observation to the actual result. Proved through the experiments that, the wave-form is clear and may be adjusted in the real-time. Besides the realization of the electric circuit is simpler and the cost is lower.
