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.

用于仿真進入（由于使用的IN0通道，所以ADDA,ADDB,ADDC均接低電平），經過模/數轉換后，產生相應的數字量經過其輸出通道D0-D7傳送給AT89C51芯片的P1口，AT89C51負責把接收到的數字量經過數據處理，產生正確的7段數碼管的顯示段碼傳送給四位LED，同時它還通過其四位I/O口P2.0、P2.1、P2.2、P2.3產生位選信號控制數碼管的亮滅。此外，AT89C51還控制ADC0808的工作。其中，單片機AT89C51通過定時器中斷從P2.4輸出方波，接到ADC0808的CLOCK,P2.6發正脈沖啟動A/D轉換，P2.5檢測A/D轉換是否完成，轉換完成后，P2.7置高從P1口讀取轉換結果送給LED顯示出來[3]。簡易數字直流電壓表的硬件電路已經設計完成，就可以選取相應的芯片和元器件，利用Proteus軟件繪制出硬件的原理，并仔細地檢查修改，直至形成完善的硬件原理圖。但要真正實現電路對電壓的測量和顯示功能，還需要有相應的軟件配合，才能達到設計要求。

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.
