This Book introduces a new architecture design for Direct Digital Frequency Synthesizer, the design is developed using top-down design flow from behavioral modeling down to the implementation process. The proposed architecture is intended for use in spread spectrum such as, frequency hopping transceiver and any other digital transceiver and aims to reduce the frequency switching time of the synthesizer and reduce power consumption of synthesizer compared to conventional designs. In order to avoid the high power consumption, no ROM is used but piecewise linear approximation is employed. The proposed architecture has been designed, simulated and synthesized using(XC4010xl) XILINX FPGA,with 3.3v supply voltage. The power consumption is 0.396 W at 100MHz clock frequency. The Spurious-Free Dynamic Range (SFDR) is better than 59 dBc at low synthesized frequencies and the frequency resolution is 1.5 kHz. This book will include an introduction to the basic DDFS architecture and explain the modification added to the conventional DDFS to improve its performance. Also it explains the types of frequency synthesizer in modern transceivers.
YALSA 2013 Best Fiction for Young Adults My Little Lore of Light is a children's version of Hajjah Amina Adil's four volume work, Lore of Light: the Stories of the Prophets of God, from Adam to Muhammad, drawn from traditional Ottoman Islamic sources. This book is intended to be read aloud to young children and to be read by older children by themselves. These abridged stories are intended to introduce a young audience to the prophets of God and to encourage thought and discussion in the family about the eternal wisdom these stories embody. Beautifully illustrated in color, the Low Power Direct Digital Frequency Synthesizer Using FPGA pdf third edition of this book is the ideal gift for Muslim children to learn the history of God's messengers on earth. This selection of twenty-seven stories shows Maupassant at his comic, cruel, and brilliant best. In addition to the poignant title story, it includes one of the most famous tales ever written, The Necklace , and Le Horla, an account of a disintegrating personality that chillingly parallels the author's own decline into madness. All the stories demonstrate his genius for invention and his ability to write unblinkingly about the absurdity of the human condition, supporting Henry James' claim that in the annals of story-telling, Maupassant stands 'like a lion in the path'. ABOUT THE SERIES: For over 100 years Oxford World's Classics has made available the widest range of literature from around the globe. Each affordable volume reflects Oxford's commitment to scholarship, providing the most accurate text plus a wealth of other valuable features, including expert introductions by leading authorities, helpful notes to clarify the text, up-to-date bibliographies for further study, and much more.
