ECET 350 Topic 3 Discussion
WEEK 3: MOVING AVERAGE FILTERS
This stock market uses moving average filters sometimes to determine the trend analysis of a stock’s performance. Discuss how you think this filtering of a stock’s value compares to filtering an input signal. Why do you think this is used for stocks? Can you think of any other applications of a moving average filter and why it would be useful?
WEEK 3: RECURSIVE AND NONRECURSIVE FILTERS
This week, both infinite (recursive) and finite (nonrecursive) filters and their responses, along with impulse and step responses, were discussed. List and discuss examples that might be seen in your daily life that might be modeled by either of these filters, and tell why you think they are either recursive or nonrecursive. Would an input to this example be a step or impulse function? For example, if you are in a large, empty room, such as a gymnasium, and someone yells out hey, what kind of input is the shout, and what is the effect or response of the gymnasium?
ECET 350 Topic 3 Lab 3: Digital Filtering and Spectral Effect
Objectives
- To learn how to determine the difference equation given FIR (Finite-impulse response) or IIR (Infinite Impulse Response) system coefficients.
- To learn how to determine the FIR transfer function based on the given difference equation, and learn how to calculate and display frequency responses of the FIR system and perform digital filtering.
- To learn how to determine the IIR transfer function based on the given difference equation, and learn how to calculate and display frequency responses of the IIR systems and perform digital filtering.
- To use Simulink FIR design tool to design various types of filters and demonstrate the filtering process by composite input signals.
