在电子技术领域中,许多电子系统及元器件的电气性能，只有在一定的电信号作用下才能显露出来，因此信号源在电子测量技术中是极其重要的,它是构建测量系统的重要组成部分。函数发生器是一种常用的信号源，广泛应用于电子电路、自动控制和科学试验等领域。它是一种为电子测量和计量工作提供符合严格技术要求的电信号设备。因此研究设计函数发生器是非常有意义的。本设计在论述了基于FPGA技术的函数发生器，在设计过程以QUARTUS II软件为平台，运用了VHDL语言设计产生正弦波、方波、三角波、锯齿波四种常用波形。用QUARTUS II 软件在Altera EP1K30TC144-3芯片上进行了逻辑综合、仿真和硬件实现，证实了设计的正确性和可行性。
In electronic field, performance of many systems and parts could be observed only in the presence of triggering signal source. So signal source is of great importance in electronic measurement, and it is an important building block of measurement system. Function generator is a common kind of signal source, widely applied in circuit, automation and experiment. It is a kind of instrument, which supplies the eletronic signal of strict technical conformation, for the electronic measurement. So it is very worthwhile to reaserch the design of function generator.
This article descripe a function generator based on FPGA，utilizing QUARTUS II as the software platform，and VHDL to generate sine ,rectangular, triangular and sawtooth wave. It has also descriped the usage of QUARTUS II software on IC Altera EP1K30TC144-3, to implement logic synthesis, emulation and hardware realization，which confirm validity and feasibility of the design.[em01][br]<p align=right><font color=red>+5 RD币</font></p> |
