adress counter

Mainly based on using EPROM, the way it works is different from those ones designed by using binary adress counter before, and makes not only hardware design be more simple but also full use of erasable and rewritable function of EPROM in coding design according to requirements of realizing various ways of counting and wavefor.

本文讨论了可程控数字信号合成技术中的计数、波形产生电路,提出了一种基于EPROM的计数、波形产生电路,取代了以往经常采用的由二进制地址计数器计数方式,从而使硬件设计大大简化,而且可以充分利用EPROM元件的可擦写功能,根据所需波形设计编码以实现各种计数及波形产生方式。
