**Part Number:**MSP430FR6047

- The absolute time of flight (absToF) is determined by a two-stage process, namely
**Acquisition**, and**tracking**, The question at hand is: How does the**tracking algorithm**determine whether a signal is arriving or not and whether it is the same as a prior signal? - how to select the effective
**Toffset**value? - Please attach a reference textbook that describes the
**correlation**,**interpolation**, and**time of flight calculation algorithms**in depth.
