【摘要】 本文提出一种采用双端口RAM实现宽频带任意波形的信号发生器的技术方法及硬件、软件的结构。该仪器利用DAC将数字量转化为模拟量来生成各种波形。由于采用双端口RAM,使得信号频率范围增加,同时可以实现任一种需要的波形。更多还原

【Abstract】 This paper presents the principle of designing a wide frequency band waveform generate based on dual port RAM, as well as hardware and software structure. The instrument utilized D/A converter to transfer digital signal into analog signal so as to form analog waveforms. because of using the dual port RAM,the frequence band has been widen, at the same time, the waveform needed can be generated at will.更多还原
