Pseudorandom binary sequence: A form of creating an M-file in the new Frequency Domain System Identification Toolbox, for a specified set of lengths (2^2-1 to 2^30-1) is called a pseudo-random binary sequence. It is also called a mlbs (Maximum Length, Binary Sequence).
Numeric precision: Numeric quantities that are represented as double-precision floating-point numbers is called numeric precision. In systems, such numbers have 53 significant binary bits, which is about 15 or 16 decimal digits.
