Logarithmic Amplifier/Detector Characterization Utilizing A Modern Vector Network Analyzer
2014-12-21 18:41:43| rfglobalnet Home Page
When characterizing the log amp/detector, a number of RF measurements must be performed. At minimum, those tests include input (S11) match, output (S22) match, and output log conformance. Log detector errors include DC output bias and slope error. Limited outputs must also be measured for absolute power and input threshold. While these tests many appear straightforward, the conventional test systems typically used to perform them often face a number of limitations. Fortunately, many of these limitations can now be overcome with just a single instrument—a modern vector network analyzer (VNA).

01.29: All Joy and No Fun: The Paradox of Modern Parenthood
2014-12-18 22:04:26| Powells Books Events Calendar
Thousands of books have examined the effects of parents on their children, but almost none have thought to ask: What are the effects of children on their parents? In All Joy and No Fun (Ecco), award-winning journalist Jennifer Senior analyzes the many ways children reshape their parents' lives, whether it's their marriages, their jobs, their habits, their hobbies, their friendships, or their internal senses of self. She argues that changes in the last half century have radically altered the roles of today's mothers and fathers, making their mandates at once more complex and far less clear. Recruiting from a wide variety of sources — in history, sociology, economics, psychology, philosophy, and anthropology — Senior dissects both the timeless strains of parenting and the ones that are brand new, and then brings her research to life in the homes of ordinary parents around the country. The result is an unforgettable series of family portraits, starting with parents of young children and progressing in later chapters to parents of teens. Through lively and accessible storytelling, Senior follows these mothers and fathers as they wrestle with some of parenthood's deepest vexations — and luxuriate in some of its finest rewards. Meticulously researched yet imbued with emotional intelligence, All Joy and No Fun makes us reconsider some of our culture's most basic beliefs about parenthood, all while illuminating the profound ways children deepen and add purpose to our lives.
