An adder logic circuit for performing an addition operation of a first numerical value and a second numerical value having a bit width narrower than that of the first numerical value is described. The adder logic circuit is composed of an adder element for performing an addition operation of the...
This divide by feature has applicati on in various types of digital coun ters.当T是高电平,切换触发器将时钟频率由两个;也就是说,如果时钟频率是8 MHz,输出频率得到触发器将4 MHz。这种“减半”功能已经应用在各种类型的数字计数器上。The above circuit shifts the conten 35、ts of the register to ...
For a high-speed test, we attached two switches at the input ports of the half-adder to control the high-speed input data by low-frequency pattern generators. The output in this measurement was an eye-diagram. Using this set-up, the circuit was successfully tested up to 20 GHz. The ...
