本文通过一种较简单的方法，设计了频率可调的正弦信号函数发生器。本文设计的正弦波发生器通过改变取点的步长实现频率可调，通过加法器获得输出点地址，调用ROM存储单元的数据，实现了正弦波发生器的设计。包括源码以及仿真结果，完整实验报告~-This article through a relatively simple method, the design of the sinusoidal signal of the frequency tunable function generator. Paper design of the sine wave generator by changing the access point in steps of adjustable frequency, the address of the output point obtained by the adder, the ROM data of memory cells is called, to achieve the design of the sine wave generator. Including source code and simulation results, a complete lab report to
