Book Description
The paper has five major sections. In the first, the periodic time varying network with N-identical paths operating between modulators is examined theoretically by the use of Laplace transforms. The transfer function is derived generally and then expanded for sinusoidal and rectangular modulation. In both cases the low-pass to band-pass characteristic is retained assuming low-pass elements in each path. The next section investigates theoretically, the effects of using other than low-pass elements in the N-paths. The results are such that, if a high-pass, first order all-pass, or a simple band-pass are used in the N-paths the resultant transfer function became a variable attenuator, a notch filter or a pair of adjacent band-pass filters respectively. The third major area is that of switching variations. A more practically oriented configuration is introduced, its transfer function variations are determined and then parallel switching is discussed. In the last sections, the real world tolerances and other variations of the components are accounted for in the transfer function of the N-path filter and their effects are noted in five disturbance categories, most serious of which are the variations in the modulating waveforms. Then finally there is a detailed implementation of an N-path filter for use in an IF of an AM/FM receiver which was introduced earlier in the literature. This application makes use of electronic bandwidth and frequency variations. (Author).

Book Description
Improving the performance of existing technologies has always been a focal practice in the development of computational systems. However, as circuitry is becoming more complex, conventional techniques are becoming outdated and new research methodologies are being implemented by designers. Performance Optimization Techniques in Analog, Mix-Signal, and Radio-Frequency Circuit Design features recent advances in the engineering of integrated systems with prominence placed on methods for maximizing the functionality of these systems. This book emphasizes prospective trends in the field and is an essential reference source for researchers, practitioners, engineers, and technology designers interested in emerging research and techniques in the performance optimization of different circuit designs.

Book Description
This book is based on the 18 tutorials presented during the 24th workshop on Advances in Analog Circuit Design. Expert designers present readers with information about a variety of topics at the frontier of analog circuit design, including low-power and energy-efficient analog electronics, with specific contributions focusing on the design of efficient sensor interfaces and low-power RF systems. This book serves as a valuable reference to the state-of-the-art, for anyone involved in analog circuit research and development.

Book Description
Masters Theses in the Pure and Applied Sciences was first conceived, published, and dis seminated by the Center for Information and Numerical Data Analysis and Synthesis (CINDAS) * at Purdue University in 1957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dissemination phases of the ac tivity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all concerned if the printing and distribution of the volume were handled by an international publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Corporation of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 24 (thesis year 1979) a total of 10,033 theses titles from 26 Canadian and 215 United States universities. We are sure that this broader base for theses titles reported will greatly enhance the value of this important annual reference work. While Volume 24 reports these submitted in 1979, on occasion, certain universities do report theses submitted in previous years but not reported at the time.
