    I know filter is which removes undesired part..

    LPF allowa only low frequency n HPF only high frequency signals..

    What is the mechanism inside it follows??

    I hav also seen equations y[n]=sigma(x[n-1])

    Why to use adders n multipliers in desining these filters??

    Pls give a clear explanation n if u hav any materials related to this pls mail me maheshkumar0459gmail.com
