Description: The Window Design Method
The basic idea behind the design of linear-phase FIR filters using the window
method is to choose a proper ideal frequency-selective filter [which always has
a noncausal, infinite duration impulse response] and then truncate its impulse
response hd[n] to obtain a linear-phase and causal FIR filter h[n]. To truncate the
impulse response of the ideal filter a time window w[n] is used. Available windows
in Matlab are rectangular [or boxcar in Matlab], bartlett, hamming, hanning Platform: |

Description: In this laboratory, we mainly focus on how to design the FIR filters using MATLAB and under certain specifications.
Also, we need to:
Design FIR filters using windows (rectangular and Hamming) to meet certain specifications
Evaluate the designed filters to see their characteristic
Realize the designed filters using some input signal sequences
Basically, we are required to get more knowledge which is about the FIR design, such as what rectangular and hamming windows are. How to obtain the most satisfactory FIR filter by adjusting the corresponding data are also important in this laboratory section.
