EEET2369 – Signals and Systems: Assignment 2 -Assignments should be submitted to Blackboard using the eReport Submission link no later than 11:59 pm on Friday 17th May 2013 (end of week 10). -The assignment is an individual task and is worth 10% of the overall course mark. -The assignment should be presented as follows: 1. Page 1: Cover Page (example): RMIT University School of Electrical and Computer Engineering EEET2369 – Signals and Systems Assignment #2 Lecturer: Dr. Katrina Neville Student Name: …….. Student Number: ……… Submission Due Date: ……. 2. Page 2 onwards: 3. Answers to questions with appropriate predictions, calculations, MATLAB graphs and discussions. 4. References: Any sources used to find out more information. I.e. textbooks, journal/conference papers, websites, etc. must be in IEEE style format. 5. Appendix: MATLAB code and other results and calculations. The assignment will be assessed on the depth of conceptual understanding shown for each task. It is important not only to present correct results/graphs/code but also to be able to analyse and discuss what your results are showing and how they link in with the concepts behind FIR and IIR filters.
Assignment 2: Design of Nulling Filters This assignment is going to examine how we can design filters that null out specific frequencies in a signal. To start with a simple nulling filter will be designed that removes a single frequency. Secondly a nulling filter will be designed to filter out multiple frequencies. a) In MATLAB design a nulling filter that filters out a single frequency. That frequency will be selected based on the 5th number in your student number (see table 1) Student Number Normalised Radian Frequency (w) ) 1 0.1p 2 0.2p 3 0.3p 4 0.4p 5 0.5p 6 0.6p 7 0.7p 8 0.8p 9 0.9p 0 0 Table 1: Frequencies to be nulled -For example if your student number was 3210987 you will design a filter to remove the normalised radian frequency: 0.9p Where normalised radian frequency is defined as: = s ff wˆ…
