phase_test
VHDL,简易音频数字相位表的设计与实现 数字相位测量仪在工业领域中经常用到的一般测量工具,主要应用与同频率正弦信号间的相位差的测量显示。
本系统采用FPGA实现测量的核心部分,主要由数字鉴相、累加计数器、控制器以及寄存与显示译码电路组成。该系统硬件电路简单,整个系统采用硬件描述语言VHDL作为系统内部硬件结构的描述手段,在XILINX公司的ISE9.1的软件支持下完成。可以对20Hz~20kHz频率范围内的音频信号进行采样鉴相处理,并将数据传回FPGA进行相位差计数累加、测量运算,最后送显示译码电路显示,测相范围为 ,相位测量误差 < 。
经测试结果验证,本系统充分利用FPGA对数据的高速处理能力,是系统设计高效、可靠,处理速度快,稳定性高,易于实现。
