SEM 2/2012 : Week 1

Digital filter is a numerical procedure or algorithms that transforms a given sequence of number into a second sequence that has some desirable properties. In electronics and mathematics digital filter is a system that performs mathematical operations on a sample, discrete-time signal to reduce certain aspects of that signal.

There is two functions of filter : 

  1. Separation of signal that have been combined
  2. restoration of signal that have been distorted in some way
For my project I heve choose to use two or more filter to make comparison between these filter. The first filter I choose is LOW PASS FILTER

LOW PASS FILTER is a electronics filter that passes low-frequencies signal but attenuates or reduce the amplitude of signals with the frequencies higher than the cutoff frequency.

For another filter I not decide yet what type of filter I want to used because I need to find the suitable filter to running with my Matlab.
