Stop changing diapers?start potting your baby. Over half the world's children are potty trained by one year old, yet the average potty training age in the United States is currently three years old. This leaves parents wondering: What did people do before diapers? and How do I help my own baby out of diapers sooner?Elimination Communication, also known as EC, is the natural alternative to full-time diapers and conventional toilet training. Although human babies have been pottied from birth for all human history, we've modernized the technique to work in today's busy world.Go Diaper Free shows parents of 0-18 month babies, step-by-step, how to do EC with confidence, whether full time or part time, with diapers or without. "Diaper-free" doesn't mean a naked baby making a mess everywhere - it actually means free from dependence upon diapers. With this book, new parents can avoid years of messy diapers, potty training struggles, diaper rash, and unexplained fussiness. Also helpful for those considering EC, in the middle of a potty pause, or confused about how to begin.This 6th edition includes a new section on The Dream Pee, a full text and graphic revision, more photos of EC in action, and a complete list of further resources.MULTIMEDIA EDITION: includes the book and access to private video library, helpful downloads, additional troubleshooting, and our private online support group run by our Certified Coaches. For less than the cost of a case of diapers, you can learn EC hands-on, the way it's meant to be learned.
This book provides a rigorous treatment of deterministic and random signals. It offers detailed information on topics including random signals, system modelling and system analysis. System analysis in frequency domain using Fourier transform and Laplace transform is explained with theory and numerical problems. The advanced techniques used for signal processing, especially for speech and image processing, are discussed. The properties of continuous time and discrete time signals are explained with a number of numerical problems. The physical significance of different properties is explained using real-life examples. To aid understanding, concept check questions, review questions, a summary of important concepts, and frequently asked questions are included. MATLAB programs, with output plots and simulation examples, are provided for each concept. Students can execute these simulations and verify the outputs.
Circuits, Signals, and Systems for Bioengineers: A MATLAB-Based Introduction, Fourth Edition, guides the reader through the electrical engineering principles that can be applied to biological systems. It details the basic engineering concepts that underlie biomedical systems, medical devices, biocontrol, and biomedical signal analysis, providing a solid foundation for students in important bioengineering concepts. Fully revised and updated to better meet the needs of instructors and students, the fourth edition expands on concepts introduced in the previous edition through computational methods that allow students to explore operations, such as correlations, convolution, the Fourier transform, and the transfer function. New medical examples and applications are included throughout the text. - Covers current applications in biocontrol, with examples from physiological systems modeling, such as the respiratory system - Features revised material throughout, with improved clarity of presentation and more biological, physiological, and medical examples and applications - Includes support materials, such as solutions, lecture slides, MATLAB data, and functions needed to solve problems
This novel book introduces speech and hearing sciences students to the principles of "signal" and "system" analysis. Beginning with an examination of what signals and systems are, the book develops a thorough background from which many of the most important issues in speech and hearing can be tackled. It is the first dedicated text on this subject. It presents techniques for speech and hearing analysis and experiments; contains minimal mathematics in describing a highly technical field; and introductory text for students in speech, hearing and psychology.
The textbook presents basic concepts of signals and systems in a clear manner, based on the author’s 15+ years of teaching the undergraduate course for engineering students. To attain full benefit from the content, readers should have a strong knowledge of calculus and be familiar with integration, differentiation, and summation operations. The book starts with an introduction to signals and systems and continues with coverage of basic signal functions and their manipulations; energy, power, convolution, and systems; Fourier analysis of continuous time signals and digital signals; Laplace transform; and Z transforms. Practical applications are included throughout. The book is also packed with solved examples, self-study exercises, and end of chapter problems.
