Sommario/riassunto |
|
This invaluable resource introduces progressive techniques for the creation of sophisticated reflectionless filter topologies that have identically zero reflection coefficient at all frequencies. Practical implementations are discussed along with their advantages when compared to classical absorptive filters and their benefits in real-world systems such as up/down converters, multiplier chains, broadband amplifiers, analog-to-digital converters, and time-domain applications. This book offers insight into the innovative process of developing reflectionless filters from first principles using both lumped elements and transmission lines. Tools for the creation of reflectionless multiplexers, matched sloped equalizers, and advanced, high-order, and nonplanar topologies are also presented. |

Sommario/riassunto |
|
This book constructs a measure of education inequality using time-series cross-national data and utilizes real-world examples based on author interviews. It provides insights into how classic trade theory might be applied more broadly to generate expectations not only about income distribution, but also about investment in human capital. The project explores the ways in which global trends toward urbanization and democratization might be expected to impact education inequality. |

The author addresses contemporary issues in politics, such as growing income inequality, the backlash against globalization and free trade, and concerns that democratic institutions are elite-dominated and unresponsive to the needs of common citizens. Nichole Torpey-Saboe is Evaluation and Research Consultant at the Colorado Department of Higher Education, USA. Her research agenda focuses on inequality, economic development, and civil society, with regional expertise in Latin America and Africa. . |
