CALENDAR ENTRY:
8826 Filter Synthesis begins with an introduction to analog filters. The course examines descriptive terminology, transfer functions and frequency response of filters; design of first order passive and active filters; design and analysis of biquad circuit, Sallen-key circuit, multiple feedback circuit and state variable filter; RC-CR transformation; inductance simulation circuit; cascade design principle; design of filters with maximally flat magnitude response; design of filters with equal ripple magnitude response; design of Bessel-Thomson filters; analysis and design of switched capacitor filters; and the use of Matlab for design of analog filters.
This course provides an introduction to the analysis, design and applications of analog filters. The aim of the course is to develop student knowledge and understanding of analog active filter design. It also aims to help students apply their mathematical skills and knowledge of analog electronics to a number of practical filter circuits. At the end of this course students will be able to specify, analyze, design and simulate analog active filters. Laboratory exercises are basically filter design and test examples. Extensive use of Matlab and Multisim is also included in the course.

There are four labs in this course that involves the design and implementation of active filters. It is mandatory for students to perform all four labs. Students are required to design and test analog active filters according to the guidelines provided by the instructor in the lab sheets available on the course website. Laboratory work is a group effort but the lab reports reflect your individual effort and your understanding of the work completed in the lab. For this reason, students are required to submit individual reports. I expect that the experimental results within a group will be the same. However, the interpretation of the experimental results should reflect your understanding of the subject matter.
Lab 1: Design a 5th order low-pass Butterworth filter with a cutoff frequency of 5kHz, Gain of 3 using a Sallen-Key circuit in the Filterlab 2 (microchip.com) and experimentally verify its magnitude and phase response in the lab.
Lab 2: Design a 5th order low-pass Chebyshev filter with a cutoff frequency of 5kHz, gain of 1, ripple of –5dB using a multiple feedback circuit in the Filterlab 2 and experimentally verify its magnitude and phase response in the lab.
Lab 3: Design and implement a 6th order Band pass Bessel filter with a center frequency of 50kHz, 3dB bandwidth of 5kHz and a center frequency gain of 2 using MAX 274 continuous time filter IC.
Lab 4: Design and implement a 4th order high pass Chebyshev filter with 4dB ripple, unity gain at DC and 2kHz cutoff frequency using a switched capacitor filter IC MF10.

ACADEMIC INTEGRITY AND PROFESSIONAL CONDUCT:
Students are expected to conduct themselves in all aspects of the course at the highest level of academic integrity. Any student found to commit academic misconduct will be dealt with according to the Faculty and University practices. More information is available at www.engr.mun.ca/undergrad/academicintegrity.
Students are encouraged to consult the Faculty of Engineering and Applied Science Student Code of Conduct at http://www.engr.mun.ca/policies/codeofconduct.php and Memorial University’s Code of Student Conduct at http://www.mun.ca/student/home/conduct.php.
LAB SAFETY:
Students are expected to demonstrate awareness of, and personal accountability for, safe laboratory conduct. Appropriate personal protective equipment (PPE) must be worn (e.g. steel-toed shoes, safety glasses, etc.) and safe work practices must be followed as indicated for individual laboratories, materials and equipment. Students will immediately report any concerns regarding safety to the teaching assistant, staff technologist, and professor.
INCLUSION AND EQUITY:
Students who require physical or academic accommodations are encouraged to speak privately to the instructor so that appropriate arrangements can be made to ensure your full participation in the course. All conversations will remain confidential.
The university experience is enriched by the diversity of viewpoints, values, and backgrounds that each class participant possesses. In order for this course to encourage as much insightful and comprehensive discussion among class participants as possible, there is an expectation that dialogue will be collegial and respectful across disciplinary, cultural, and personal boundaries.
STUDENT ASSISTANCE: Student Affairs and Services offers help and support in a variety of areas, both academic and personal. More information can be found at www.mun.ca/student.
