Systems and methods for transporting intravascular devices through a body lumen are disclosed. The technology allows switching between streams at pre-determined points without the introduction of audible artifacts. Next, a first correlation sequence between the complex conjugate of the sample sequence and the sample sequence with a lag of N samples is formed.
