To write data to the FIFO, present the data to be written and assert the write enable. At the next rising edge of the Clock, the data will be written. For every rising edge of the Clock that the write enable is asserted, a piece of data is written into the FIFO. If the FIFO has data in it, the value at the head of the FIFO is present on the FIFO data output. To read data from the FIFO, assert the read enable. At the next rising edge of the Clock, capture the data output the FIFO will subsequently advance to the next piece of data stored in the FIFO.

用于仿真进入（由于使用的IN0通道，所以ADDA,ADDB,ADDC均接低电平），经过模/数转换后，产生相应的数字量经过其输出通道D0-D7传送给AT89C51芯片的P1口，AT89C51负责把接收到的数字量经过数据处理，产生正确的7段数码管的显示段码传送给四位LED，同时它还通过其四位I/O口P2.0、P2.1、P2.2、P2.3产生位选信号控制数码管的亮灭。此外，AT89C51还控制ADC0808的工作。其中，单片机AT89C51通过定时器中断从P2.4输出方波，接到ADC0808的Clock,P2.6发正脉冲启动A/D转换，P2.5检测A/D转换是否完成，转换完成后，P2.7置高从P1口读取转换结果送给LED显示出来[3]。简易数字直流电压表的硬件电路已经设计完成，就可以选取相应的芯片和元器件，利用Proteus软件绘制出硬件的原理，并仔细地检查修改，直至形成完善的硬件原理图。但要真正实现电路对电压的测量和显示功能，还需要有相应的软件配合，才能达到设计要求。

Do you have a mobile phone? We think you probably do, one way or another. We would also guess that you might use it for many diff erent things in the course of your everyday life—as a telephone certainly, but also as an address book, as a Clock or watch, as a camera, or now as a connection to your computer, email and the internet. Th ere will be a range of people you use it to contact (or not), and various strategies you use to take calls—or send texts, or take photos, or receive emails, or search online (or not, in diff erent situations). Th ere are also likely to be a range of social relation- ships in your life that your mobile phone helps to maintain—or disrupts, or inter- venes in, or makes possible, or complicates, or just plain helps to handle.

his research aims at creating broadband tunable, fully integrated filters for the application of cognitive radio and signal classification receivers. The approach under study is the N-path filter technique which is capable of translating a baseband impedance to a reference frequency creating a tunable filter. The traditional N-path filter suffers from fundamental architectural limitations, namely : a trade-off between insertion loss and out-of-band rejection, reference Clock feed- through, and jammer power handling limitations. In the first approach, the fundamental trade- off of the traditional N-path filter between insertion loss and out-of-band rejection is improved by a transmission line (T-line) N-path filter technique.
