The principles of signal processing are fundamental to the operation of many everyday devices. This book introduces the basic theory of digital signal processing, with emphasis on real-world applications. Sampling, quantization, the Fourier transform, filters, Bayesian methods and numerical considerations are covered, then developed to illustrate how they are used in audio, image, and video processing and compression, and in communications. The book concludes with methods for the efficient implementation of algorithms in hardware and software. Intuitive arguments rather than mathematical ones are used wherever possible, and links between various signal processing techniques are stressed. The advantages and disadvantages of different approaches are presented in the context of real-world examples, enabling the reader to choose the best solution to a given problem. With over 200 illustrations and over 130 exercises (including solutions), this book will appeal to practitioners working in signal processing, and undergraduate students of electrical and computer engineering.

A critical examination of an increasingly vital role in surgical practice Surgical first assistants (SFAs) are registered nurses or operating department practitioners (ODPs) who play a crucial role in the operating theatre during surgical procedures. Under the direct supervision of the operating surgeon, an SFA provides continuous skilled assistance, performing a range of established responsibilities to assist the surgeon predominantly in the intraoperative phase of the patient’s journey, but also in the pre- and post-operative phases. The role affords theatre nurses and ODPs the opportunity to expand their clinical responsibilities and provide assistance for patients undergoing surgery by undertaking post-qualifying education. More recently, an understanding of the knowledge and skills of the SFA role has been embedded into the undergraduate curricula for ODPs. Surgical First Assistant: The Essentials of Practice provides a comprehensive and critical examination of the knowledge, skills and behaviours that are required by SFAs to ensure patient safety and quality care. Beginning with a historical overview of the SFA role, it proceeds to outline the legal, ethical and professional aspects of the role which allows the practitioner to critically reflect on SFA practice. It also offers an in-depth analysis of the SFA’s responsibilities as defined by the Perioperative Care Collaborative through each phase of the patient’s perioperative journey from pre-operative assessment to post-operative pain management. Surgical First Assistant readers will also find: A text aligned with UK national standards and best practiceDetailed discussion of topics including pre-operative preparation with the operating theatre, assisting with haemostasis, and many moreAn approach which explores both the technical and non-technical skills required by the SFASurgical First Assistant is ideal for registered nurses, ODPs, student and apprentice operating department practitioners.
