A Little MLS Tutorial

by Robert Bristow-Johnson

A Maximum-Length Sequence (MLS) has two different (but related) definitions:

One is the driving function applied to the input of a linear time invariant (LTI) system:

   x[n] = X*(-1)^a[n]

The other definition is simply the binary sequence, a[n] = 0 or 1, used in the exponent.
