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.
