一种任意波形发生器的设计

Design of a Kind of Arbitrary Waveform Generator

提出了一种任意波形发生器(AWG)的设计方法,基于现场可编程门阵列(FPGA)的任意波形发生器采用直接数字频率合成(DDS)技术,用硬件描述语言Verilog HDL编程实现。采用该方法设计的任意波形发生器输出的波形具有平滑、稳定度高、频率稳定度和分辨率高等众多优点。

A design method for a kind of arbitrary wavefonn generator （AWG） was put forward. The AWG based on a field programmable gate array （FPGA） adopted direct digital frequency synthesis （DDS） technology and hardware description language, Verilog HDL to program. The designed AWG has many strong features, such as smooth and stable waveforms, stable frequency and high resolution etc.
