Filtering and eigenfnction

  1. Jan 23, 2006 #1
    I don’t know if I understand eigenfunction correctly, I hope someone can help me with it.
    By definition of eigenfunction as
    Af=Lf ;
    Is it correct to say that filtering (A) is equal to scaling (L) through representation of a function by eigenfunction (f) ?

    An eigenfunction is a waveform that only gets scaled when going through a linear time-invariant (LTI) system. The scaling constant is the eigenvalue.
