This 86-page book presents basic and advanced concepts in circuit dynamics - the circuit theory of frequency response, risetime, bandwidth, open-circuit time constants, Miller's frequency-dependent theorem, the Extra Element Theorem (EET), ZEET, Blackman's Z Theorem, the Cochrun-Grabel method for finding circuit poles, strategies for maximizing circuit performance involving stage isolation and pole separation, and the ability to analyze amplifiers by modularizing and controlling stage interfacing. It supplies derivations and more detail than the author's book, Transistor Amplifiers. It corrects some popular misconceptions about calculating bandwidth, fills in neglected high-frequenc ...

From the Landplane Preface > ...this Guide attempts to present the essentials of safe and technically sound flight testing to the E-AB pilot community in a practical, easy to understand way. The flight test topics deemed important to E-AB flight testing derive directly from NTSB recommendations and latest FAA guidance. They represent a mixture of test philosophy and how-to-do-it flight test techniques subjects with an overall emphasis on best practices and safe test conduct. From the Landplane and Seaplane Preface > … there are differences in test procedures between landplanes and seaplanes and they deal with their ground and water handling regardless of whether or not the airplanes ...

This flight test guide presents the essentials of safe and technically sound flight testing to the amateur-builder pilot community in a practical, easy to understand way. The flight test topics deemed important to amateur-builder flight testing derive directly from NTSB recommendations and latest FAA guidance. They represent a mixture of test philosophy and “how to do it” flight test techniques subjects with an overall emphasis on best practices and safe test conduct.

The anode to cathode distance of a Hall cell is an important parameter to understand and control. If it is excessively large energy is wasted. If it is too small current efficiency is reduced. If smaller yet, the cell will become unstable. The anode to cathode distance is adjusted by moving the anode bridge to control cell resistance. It is generally assumed in resistance calculations that the bottom of the anodes are in one plane. It is also generally assumed that the cathode surface, which is the liquid metal, is static. Thus the anode to cathode distance is generally assumed to be the distance between the two parallel planes. In this paper, a simple and accurate method will be des ...

Power input to a cell is the product of volts and current and is therefore two dimensional. In this paper, we will use two dimensional charts to visually illustrate the power input to a cell used to make aluminum and the power used to maintain the cells heat balance. In doing so, we will also explore the power efficiency of the cell as well as defining other related efficiencies.

In slightly more than 100 years, the electrochemical production of aluminum from aluminum oxide has grown from invention to the technology of today. The single most important change related to efficiency improvement was the application of computer control. Within computer control, the two most important programs are resistance control and alumina feed control. Within the resistance control program, the formula used to calculate a cell’s resistance utilizes a constant that is assumed to be the intercept of the resistance line at zero current. In reality, the intercept is lowered by leakage current and therefore reflects current efficiency loss due to the leakage current. The purpose o ...

Want to design your own PCBs? Don't know where to start? This book's got you covered! It's a manual on how to think about where the parts go, not just what mouse moves to do. It is aimed specifically at someone who wants to convert a schematic diagram into a practical printed circuit board. The design process is explained from schematic parts all the way down to optimizing placement and routing. The most recent edition here includes not only through-hole parts but also extension to surface mount part layout. The author has designed PCBs for decades. You can do it too!

This book considers two process capability indicators (Cp,Cpk) in combination with four measurement system capability indicators and explores their mathematical relationships. This is motivated by a critical need to understand the impact a measurement system may have on a process assessment.
