TYPES OF NOISE













                       Uncorrelated                                           Correlated

                1             Noise                                                Noise


                                                                              No signal, No noise
                     Always has noise in the
                               system                                  A  type  of  internal  noise  that
                   Exist regardless of whether                         that is dependent on the signal

                    there is a signal present or                       and  is  mutually  tied  to  it;  in
                                 not.                                  other words, without the signal,
                                                                       the  noise  cannot  exist  in  a
                                                                       circuit.
