In the second article, 2 I examined the phase shift of the filter transfer function for the low-pass and high-pass responses. This article will concentrate on the band-pass response. While filters are designed primarily for their amplitude response, the phase response can be important in some applications. For purposes of review, the transfer function of an active filter is actually the cascade of the filter transfer function and the amplifier transfer function see Figure 1. Figure 1.

David G. Long, Professor long ee. Text: class notes D. Comer, Continuous Time Filters available from the instructor in. Jarry and J. Schaumann and M. My goal is to help you develop intuition and real understanding. While understanding the mechanics of using engineering concepts and techniques is, of course, critical, knowing when to apply a given technique can be even more important. I believe that my role as an instructor is to expound upon the reading material and homework and provide additional examples and explanations as needed.
It is your responsibility to read the reading assignments prior to coming to class and participate in the class by actively listening and asking questions in order to understand the material. Tests are designed to evaluate your ability to apply what you have learned. Homework assignments are designed to reinforce what you have learned and provide practice using what you have learned.
Since this is a graduate course, the homework will be assigned but not graded. Your grades will be based on your test performance and a project report. Reading: Reading will be assigned in each class period for the next period. Readings will be primarily from the text but may include additional sources and handouts.
Project: There is no substitute for practical experience. Thus, each student will be required to design, build, and test a practical filter. This work will be documented in well-prepared report pages, single space, with figures.
You can select one project from a list provided, or propose one of your own. The mid-term exam will be administered in class on a date to be determined. The final will be comprehensive. I give partial credit. Note: no late exams will be given. Let me know in advance of a problem attending an exam. Homework: Homework will not be graded. I encourage you to work together on the homework. Honor Code: You will be expected to observe all aspects of the BYU honor code including the dress code. Your exams and reports must be your own work.
From the University instructions: "In keeping with the principles of the BYU Honor Code, students are expected to be honest in all of their academic work.
Academic honesty means, most fundamentally, that any work you present as your own must in fact be your own work and not that of another. Violations of this principle may result in a failing grade in the course and additional disciplinary action by the university.
Students are also expected to adhere to the Dress and Grooming Standards. Adherence demonstrates respect for yourself and others and ensures an effective learning and working environment. Please call the Honor Code Office at if you have questions about the honor code. Legal Stuff: Preventing Sexual Harassment. Title IX of the Education Amendments of prohibits sex discrimination against any participant in an educational program or activity that receives federal funds.
The act is intended to eliminate sex discrimination in education. Title IX covers discrimination in programs, admissions, activities, and student-to-student sexual harassment. If you encounter unlawful sexual harassment or gender based discrimination, please talk to your professor; contact the Equal Employment Office at or hours ; or contact the Honor Code Office at Students With Disabilities: Brigham Young University is committed to providing a working and learning atmosphere which reasonably accommodates qualified persons with disabilities.
If you have any disability which may impair your ability to complete this course successfully, please contact the Services for Students with Disabilities Office Reasonable academic accommodations are reviewed for all students who have qualified documented disabilities.
Services are coordinated with the student and instructor by the SSD Office. If you need assistance or if you feel you have been unlawfully discriminated against on the basis of disability, you may seek resolution through established grievance policy and procedures.

Includes bibliographical references p. Contents Approximation-- sensitivity-- passive network synthesis-- single-amplifier active RC filters-- multi-amplifier active RC filters-- direct realization methods-- passive low-pass filter realizations-- network functions with elliptic magnitude characteristic-- properties of operational amplifiers. The book is designed to lead smoothly from basic background circuit theory into the details of modern analog filter theory. The treatment not only covers a study of the basic filter structures, but also introduces advanced topics including sensitivity, operational amplifier gain bandwidth effects and compensation. Its complete coverage of modern approximation allows students to study all types and enables comparative studies of different filter realizations because of the use of computers in filter design. Many computer methods are introduced, emphasizing design and applications.
