1- Aliasing can affect DFTs, where higher frequency signals canappear as lower frequency signals due to the use of an N point DFTthat has a limit to the highest frequency it can detect. Give oneapproach when using a DFT to reduce the potential of aliasing.
2-. Ă‚Â Ă‚Â When using the standard MATLAB commands, or thedesign equations, to design an FIR filter why is it a good idea tocheck if the design meets requirements ? Be specific.
3-When using the bilinear transform what is meant by“pre-warping” and why is it necessary ?
4- When using one of the classic filter approximations, whichapproximation should be used if :
- the minimum amount of output distortion is desired.
b. the minimum filter order is desired.
5- Give one advantage of using an FIR filter and onedisadvantage of using an FIR filter, when compared to an IIR filterdesign for the same specification.
Advantage:
Disadvantage:
